  • A patch discrete material optimisation method for ply layout of wind turbine blades based on stiffness matrix material interpolation   Order a copy of this article
    by Jinshun Yan, Pengwen Sun, Penghui Wu, Lanting Zhang, Weifei Hu 
    Abstract: A patch discrete material optimisation (PDMO) approach is proposed interpolated by stiffness matrix material for wind turbine blade (WTB) ply layout. Unlike the usual methods, the stiffness matrix is applied to replace the constitutive matrix for material interpolation in this research. The elemental stiffness matrix can be derived directly from the finite element analysis (FEA). It is possible to alleviate the programming work of numerically integrating the constitutive matrix. Moreover, the patch strategy may reduce the number of design variables and effectively satisfy the practical design requirements. The numerical example of a thin plate verifies the feasibility and effectiveness of the PDMO method. In the case study, a patch optimisation of the ply parameter for a 1.5 MW blade is conducted. Results indicate that the maximum displacement reduction of the optimised blade is from 4.1% to 17.5% compared to the blade displacement of the blade utilising the original ply scheme.
    Keywords: patch discrete material optimisation; PDMO; material interpolation; stiffness matrix; ply layout; wind turbine blade; WTB.

  • Fatigue life of aircraft structure in corrosion and pollution environment   Order a copy of this article
    by Ran Zhuo 
    Abstract: With the development of science and technology, the application of aircraft is more and more extensive, and corrosive pollution has caused great obstacles to the operation of aircraft. In this paper, a quasi-normal distribution model is proposed to calculate the corrosion pollution environment and aircraft structure damage, and three sets of experiments are carried out for static tension, conventional environment corrosion and accelerated corrosion. Because the normal distribution is a natural distribution and is not affected by human beings, and the atmospheric environment is a natural environment that can be more in line with the normal distribution, this paper proposes a tentative normal distribution model for corrosion prediction calculations. This paper can predict the fatigue life of aircraft structures in corrosive and polluted environments, with an accuracy rate of over 95%.

  • RSM-based optimisation of machining forces and surface roughness when laser-assisted turning Nitinol alloy   Order a copy of this article
    by Chakala Naresh, P.S.C. Bose, N. Selvaraj 
    Abstract: In the current investigation, the interrelation between parameter attributes, namely, laser power, cutting speed, feed rate, and depth of cut on machining forces [thrust force (Fx), feed force (Fy) and cutting force (Fz)] and surface roughness (SR) in laser-assisted turning (LAT) of Nitinol alloy using TiAlN PVD coated carbide inserts has been discussed. Experiments were performed using response surface methodology (RSM) and face centred central composite design (FCCD). Statistical techniques such as analysis of variance (ANOVA) and RSM were used to evolve regression models and to arrive at optimum parameter attributes. Results from the current research suggests that cutting speed and feed rate have superior impact on thrust force and cutting force, while feed rate and laser power are the most prominent important attributes for feed force. For SR, speed and cutting depth are the most prominent attributes. The optimum LAT parameters obtained through desirability function include power of 450 watts, cutting speed of 75 m/min, feed of 0.025 mm/rev and depth of cut of 0.5 mm with predicted machining forces of Fx = 123 N, Fy = 154 N and Fz = 102 N and surface roughness of 0.653 μm at 0.995 desirability level.

  • Investigation of corrosion behaviour of boronised cold rolled high manganese steel   Order a copy of this article
    by Cihangir Tevfik Sezgin, Fatih Hayat 
    Abstract: Corrosion behaviour of boronised high manganese steels (HMS) was investigated in this study. Pack-boronising was processed at 950°C, 900°C and 850°C for 2 h, 4 h, and 6 h. Boride layers of HMS unpredictably exhibited saw-tooth morphology. FeB, Fe2B, MnB and SiC phases were determined by XRD analyses. The increase in boronising temperature and time caused an increase in boride layer thickness. Although the corrosion rates were lower in boriding processes at 850°C, the corrosion rate of most of the samples boronised at 900 and 950°C was higher than the un-boronised HMS due to micro-cracks and pores formed in the boride layers.
    Keywords: corrosion; boronising; high manganese steel.

  • Optimising the drilling process parameters of Kevlar-epoxy composite material using the experimental design-based goal programming approach   Order a copy of this article
    by Yusuf Tansel İç, İmdat Kara 
    Abstract: In this study, we present an experimental design-based goal programming approach to determine the optimum values of the cutting parameters in the drilling process of Kevlar-epoxy composite material. As a result of the experiments, we measured the surface roughness and delamination factor of the drilling hole. We obtained the regression functions for surface roughness and delamination using the 2k factorial design approach. Then, the cutting parameter values that will optimise the delamination and surface roughness were found with the goal programming method. The difference between the presented study and the published studies in the literature is that it proposes an integrated experimental design and goal programming approaches to find the optimal parameter values for different target values to minimise surface roughness and delamination at the same time. We have concluded that the proposed method is suitable considering different goal values for obtaining the optimum drilling parameters.
    Keywords: Kevlar-epoxy composite material; delamination; experimental design; surface roughness; goal programming; factorial design; drilling; optimisation.

  • Comparative analysis of different multi-criteria decision-making techniques for materials selection of filler reinforced thermoplastic composite   Order a copy of this article
    by Ashish Soni, Pankaj Kumar Das, Mrinal Jyoti Sarma 
    Abstract: Material selection plays a significant role in the workability of a product which can be effectively implemented with the aid of multi-criteria decision-making (MCDM) techniques. In the present study, the rankings of alternatives as particulates filled thermoplastic composite materials was carried out by using MOORA, TOPSIS, and COPRAS for the desirable performance. The physical, mechanical and tribological properties were the defined criteria for the selection of alternatives. For weightage of the criteria, the analytic hierarchy process (AHP) was used. The consistency of the criteria weightage was verified through the consistency index and consistency ratio of 0.1104 and 0.0985, respectively and eigenvalue (?max) of 5.4416. The ranking results were compared by using Spearman’s rank correlation coefficient. Empirical findings suggested 70 wt. % of polypropylene, 15 wt. % of RHA and 15 wt. % of sand as the best compositions for polymeric composite material. The study validated the stability of the ranking results the MCDM techniques. The study will support the researcher and industrial managers in material selection of polymeric composites.

  • Flexural behaviour of CFRP RC beams having a ductile cementitious composite layer in compression zone: an analytical study   Order a copy of this article
    by Nooshin Ghorbani Amirabad, Farshid Jandaghi Alaee, Meysam Jalali 
    Abstract: Today, the use of fibre reinforced polymer (FRP) bars has received considerable attention. However, concrete beams reinforced with FRP bars suffer from a lack of ductility. The addition of steel bars to the beams has been widely studied to improve ductility. In this study, the idea of using a ductile cementitious composite layer (DCCL) in the compression zone is investigated. In fact, the ductility of DCCL comes from the bridging action of fibres and confinement concepts rather than the yielding of steel members. First, an analytical model is proposed to predict the behaviour of the beams. Then, the behaviour of concrete beams reinforced with FRP bars having various DCCL layers is investigated. It is shown that using DCCL can improve the ductility of the beams. The ductility ratio of the beam with a layer of DCCL is 3.5 times more than that of the control beam.

  • Compressive behaviour and energy absorption capacity of a lattice structure generated by topology optimisation   Order a copy of this article
    by Tomohisa Kojima, Yuta Takase, Tomoaki Tsuji 
    Abstract: Research on micro-lattice structures has been actively conducted along with the development of additive manufacturing; this is because properly designing the unit cell structure can help achieve various mechanical properties, such as ultra-lightweight, high strength, and high energy absorption capacity. Furthermore, the development of design strategies can yield advanced tailored properties. This study aimed to explore a new design strategy for micro-lattice structures with high energy absorption capacity. A unit cell shape was designed using topology optimisation, after which finite element analysis was conducted to investigate the compressive response and energy absorption capacity of the designed lattice structure. Different unit cell structures resulted in different deformation patterns of the struts, changing the stress-strain relationship in the entire structure. The structure of the topology-optimisation-designed unit cell exhibited the highest stiffness and the possibility of the highest energy absorption capacity, which can be improved by controlling the stress-strain relationship.

  • Processing of natural lignocellulosic coir fibres for enhanced flame retardancy using aluminium trihydrate   Order a copy of this article
    by Simimol Ansera, Ajith Sudhakaran, Anita Ravindranath 
    Abstract: The high lignin cellulose ratio in coir fibres makes it more susceptible to fire, whereby coir and its allied products are pushed back away from fire retardant applications. These fibres are subjected to treatments by soaking in hot dilute solution of aluminium trihydrate for enhanced fire retardancy. The treated fibres exhibited improved flame retardant properties with reduced water absorption and showed no remarkable change on the physical and mechanical characteristics. The time of burning was significantly reduced from 182 to 65 seconds and the treated fibres did not produce smoke when burnt. The flame propagation rate was reduced by 2.5 times and limiting oxygen index elevated by 1.2 times compared to the raw fibre. As a low toxic, sparingly soluble substance, aluminium trihydrate is a better halogen-free fire retardant addition for coir fibres in product manufacturing in the coir sector.
    Keywords: coir fibre; flexural rigidity; flammability; tensile strength; fire retardancy.

  • Effect of polyvinyl alcohol to starch ratio on the nutrient release and water absorption behaviour of slow release fertiliser   Order a copy of this article
    by Ayushman Panda, Shyama Prasad Mohanty 
    Abstract: In the present study, polyvinyl alcohol (PVA) has been blended with starch to confine the fertiliser particles in the polymer matrix. NPK fertiliser particles have been embedded in polymer matrix by a solution casting method. Different weight ratios of PVA to starch, that are 7:3, 5:5 and 3:7 have been investigated. Morphologies of the samples have been studied using optical microscopy. Higher content of PVA in composition leads to a smooth surface of film. The prepared samples have been characterised by ionic conductivity measurements and water absorption tests to estimate the fertiliser release rate and water retention capacity, respectively. Sample containing higher content of PVA shows lower change in ionic conductivity and hence, lower release of nutrients in 24 h of soaking in distilled water. Among the three samples, composition having PVA to starch ratio of 5:5 shows uniform surface, higher water retention characteristics and thereby, better slow release capabilities.

  • Experimental investigations for the characterisation of an SMA-bias spring actuator in a flexible tube manipulator   Order a copy of this article
    by Nisha Bhatt, Sanjeev Soni, Ashish Singla 
    Abstract: The present article describes an application of shape memory alloy (SMA) spring-based actuator for the development of a flexible tube manipulator intended for tumour irradiation application. A constitutive model is proposed that incorporates the nonlinearity of SMA spring along with the loading history of material and predicts 4 N as the force generation capability of the SMA-bias spring actuator. The simulation results follow the characteristic profile of SMA in both normal as well as cyclic loading conditions. Further, experimental characterisation of the actuator is carried out to determine various parameters like modulus of rigidity, critical shear stresses, etc. and a proportional integral derivative (PID) controller is experimentally implemented which made the tip of the tube following a series of predefined points. The maximum positional error is around 5%, which shows the positional tracking ability of the developed manipulator and the maximum bending angle of the tube is 74.6

  • Analysis of multi-layer solid lubricating film on improving the corrosion resistance of transmission gears   Order a copy of this article
    by Weihua Liu 
    Abstract: The corrosion resistance of transmission gear was studied by covering the surface of transmission gear with multi-layer solid lubricating film. First, the friction characteristics of the solid lubricating film are analysed, the transmission torque of the transmission gear is obtained by the law of conservation of energy, and the relationship between the deflection angle and the wear depth of the transmission gear is determined; finally, the corrosion parameters of single-layer solid lubrication film and composite multi-layer solid lubrication film are compared in seawater environment to verify the corrosion resistance of transmission gear. The experimental results show that the multi-layer solid lubricating film can effectively improve the corrosion resistance of transmission gears. When the corrosion time is 12 days, when the BN content is 20wt.% and 30wt.%, the corrosion rate is as low as 0.0050 g/(m2 h) and 0.0037 g/(m2 h) respectively.

    by Lei Zhang, Yingying Fei 
    Abstract: In order to effectively remove heavy metal pollutants and improve the quality of the ecological environment, the experimental study on adsorption properties of functional magnetic nanomaterials for heavy metal pollutants was studied. Magnetic nano-Fe3O4 materials were prepared by hydrothermal method. Fe3O4, Fe3O4@SiO2 and 3NH2-Fe3O4@SiO2 magnetic nanomaterials were obtained by functional modification. The adsorption properties of functionalised magnetic nanomaterials for Cd(II) and Pb(II) in water were analysed by batch test. The results show that 3NH2-Fe3O4@SiO2 has the highest adsorption capacity for Cd(II) and Pb(II); with decreasing temperature, the order of adsorption capacity for Pb(II) is Fe3O4 > Fe3O4@SiO2 > 3NH2-Fe3O4@SiO2. The Langmuir adsorption isotherm model can better fit the adsorption process of functionalised magnetic nanomaterials to Cd(II) and Pb(II) solutions; in different initial heavy metal solution concentration systems, the materials can promote the adsorption of Cd(II) and Pb(II) adsorption.

    Abstract: In this paper, the double-horizontal-shaft vibrating mixer is taken as the research object, and the effect of the vibrating mixing on the performance of UHPC materials are contrasted and analysed in simulations and tests. Firstly, a three-dimensional model of the double-horizontal-shaft vibrating mixer is constructed, and the EDEM software is imported for simulation analysis. Then, on the premise that materials are fully mixed in the model, a set of contrastive studies between the non-vibrating mixing and vibrating mixing was designed. The post-processing function of the EDEM software is used to analyse the material movement after mixing and the rule of the material uniformity changing over time. Finally, various performances of the material are tested in field tests. Overall, for UHPC preparation, the effect of the vibrating mixing is better than that of the non-vibrating mixing.

  • Experimental investigation on the effect of process parameters on machinability and surface integrity during end milling of Mg-TiO2 nanocomposite   Order a copy of this article
    by Ganesh Radhakrishnan 
    Abstract: In this study, end milling experiment was performed on magnesium matrix nanocomposites with TiO2 proportion of 1.5, 2.5 and 5 wt.% respectively under dry condition using Ti-AlN coated tungsten carbide tool. The tomographs of the specimens revealed the fact that there was no significant agglomeration. Mg-5% TiO2 experienced better mechanical properties compared to that of other composite and pure Mg specimens. The microhardness and nanohardness was maximum for Mg-5% TiO2 of about 63.89 Hv and 1.24 GPa respectively. The irregular crystalline structure of hard ceramic TiO2 nanoparticulates and its bonding with the soft Mg matrix affected the machinability significantly. The maximum cutting force was observed for Mg-2.5% TiO2, which is in the range of 10 to 14 N, whereas the maximum cutting temperature of approximately 32 C was observed for Mg-5% TiO2. The interfacial bonding between TiO2 and Mg due to increase in concentration of TiO2 affects the machinability of nanocomposite to a greater extent than that of machining conditions. Ploughing phenomenon dominated at higher concentration of TiO2 which in turn affected the surface integrity of machined nanocomposites. Higher order of surface roughness was noticed for Mg-5% TiO2 of about 0.5 m at spindle speed of 1,500 rpm.
