International Journal of Computational Materials Science and Surface Engineering (IJCMSSE)

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 Articles will not be published until the final proofs are validated by their authors.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.

  • Numerical Modelling of the Electromagnetic Forming of Seamless Steel Tube Compression Process   Order a copy of this article
    by Thirupathi Nadimetla, Lalit Kumar, Sachin Kore 
    Abstract: This study explores Electromagnetic Forming (EMF), a contactless metal shaping method using intense magnetic fields to deform conductive metal beyond plastic limits. LS-DYNA software simulates EMF processes on steel tubes with a 76.2 mm outer diameter and a 71.40 mm inner diameter, employing a 9-turn solenoidal coil. The analysis covers displacement, velocity, magnetic fields, Lorentz forces, and stresses at different energy levels (8 kJ, 12.8 kJ, 15.8 kJ). The study validates LS-DYNA's accuracy and establishes a direct correlation between higher energy input and increased electromagnetic parameters. Higher energy levels result in proportional increases in Lorentz forces, electromagnetic pressure, magnetic field strength, radial displacement, deformation velocities, and stress at the tube's midpoint. The findings underscore energy's pivotal role in electromagnetic compression processes. This comprehensive study, integrating numerical simulations and experimental validation, offers valuable insights for practical applications of EMF in high-strain metal forming, contributing to advancements across industries.
    Keywords: Electromagnetic forming; seamless tube compression; FEM analysis; LS-DYNA; Lorentz forces; Stress-strains distributions.

  • Multi Objective Optimization of the Engine Connecting Rod Based on the Response Surface Methodology   Order a copy of this article
    by Bin Zheng, LinFei Zhou 
    Abstract: As one of the most important parts of the internal combustion engine, the connecting rod plays a key role in transforming the reciprocating linear motion of the piston axial direction into the rotating motion of the crankshaft. Therefore, the structural design of the connecting rod directly affects the service life of the engine. Aiming at the low efficiency and limitation of traditional methods in the optimization design of connecting rods, an optimization design method combining the response surface model and multi-objective genetic algorithm is proposed. Firstly, the static and dynamic characteristics of the connecting rod are analyzed under typical working conditions. The five dimensional parameters of connecting rod, namely, the small end depth (x1), the shank depth (x2), the arc between the small end and shank (x3), the arc between the large end and shank (x4), the shank groove depth (x5) are chosen as design variables by using sensitivity analysis. Then, the deformation, the maximum equivalent stress, and the first-order, second-order, and third-order natural frequencies are taken as objective functions.
    Keywords: connecting rod; finite element analysis; experimental design; numerical simulations; sensitivity analysis; response surface methodology; multi objective optimization.
