Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Prioritisation of self-curing self-compacting mortars with hydrophilic chemicals using MCDM techniques   Order a copy of this article
    by Degloorkar Nikhil Kumar, Pancharathi Rathish Kumar, S.A. Reddi, Sri Rama Chand Madduru 
    Abstract: Decision making becomes complex and challenging when a wide range of alternatives and conflicting criteria are involved in the problem. Selection of an ideal repair material is one such problem. Self-curing compounds namely polyethylene glycol (PEG) inhibits the evaporation of internal water in mortar mixes. In this study, a set of Self-Compacting mortar mixes Mix A (1 : 1) and Mix B (1 : 3) with varying dosages of PEG4000 and PEG200 (0.1%, 0.5% and 1%) by mass of cement is studied. Slump flow, V funnel time, compressive strength, sorptivity coefficient and Acid Durability Loss factor were the specific criteria considered in applying MCDM techniques (TOPSIS and PSI) to arrive at best mix proportion among different mortar mix alternatives. Among the alternatives, it was observed that the Mix A (1 : 1) with 1% dosage of PEG4000 (AH-1 mix), was observed to be the best alternative mortar.
    Keywords: self-compacting mortar; PEG; polyethylene glycol; hydrophilic; TOPSIS; technique for order preference by similarity to ideal solution; PSI; preference selection index; ADLF; acid durability loss factor.

  • Optimisation of EDM process parameters: by butterfly optimisation algorithm and genetic algorithm   Order a copy of this article
    by Shubham Jain, Vishal Parashar 
    Abstract: In this paper, parametric single-objective optimisation and multi-objective optimisation for electric discharge machining (EDM) on En-24 steel has been carried out by butterfly optimisation algorithm (BOA) and Genetic Algorithm. In this research, different process parameters like Peak Current (Ip), Pulse ON Time (Ton), Gap Voltage (Vp) have been selected to optimise the responses like material removal rate (MRR) and surface roughness. A central composite design (CCD), for three machining parameters at five-level each, has been selected to design the experiments. Analysis of variance (ANOVA) has been performed to find significant process parameters affecting responses and the validity of the derived modal in the present work. The grey relational analysis method has been used to find the optimum weightage for all responses. The comparison found that the BOA gives very close results to the Genetic Algorithm so that BOA can be applied for real-world optimisation problems.
    Keywords: ANOVA; analysis of variance; CCD; central composite design; EDM; electric discharge machining; grey relational analysis; multi-objective BOA; butterfly optimisation algorithm.

  • Design of gating system for propeller casting through melt flow simulation   Order a copy of this article
    by Amir Hosein Riazi, Seyed Mohammad Ali Boutorabi, Mohammadreza Aboutalebi, Mohsen Ostad Shabani 
    Abstract: Marine propellers have a complex geometry and uneven thickness, which causes severe and unpredictable problems during the casting process. Designing a proper gating system leads to the production of clean and sound castings. In this paper, a computer modelling study was carried out for casting of a marine propeller using a commercially available software package was used to explore the improvement of filling systems based on the relatively new concepts of avoiding entrainment of air bubbles and oxides by avoiding surface turbulence. In the simulation process, bottom-pour and top-pour designs were considered, which were examined in 7 trials. Since a critical velocity of 0.5 m/s is required to produce clean and sound castings, suitable methods were used to reduce the melt velocity to 0.5 m/s. This obtained results out of this research paper confirm that the use of a filter, an extended runner, and a fan gate is favourable for reducing the melt velocity along the melt path.
    Keywords: simulation; extended runner; casting; propeller; filter; fan gate.
