A micromechanics framework for the development of continuum-level constitutive models for the large-strain deformation of porous hyperelastic materials is presented. A kinematically admissible deformation field is assumed which enables... more
The large-strain constitutive behavior of cold-rolled 1018 steel has been characterized at strain rates ranging from $\dot \varepsilon = 10^{ - 3} $ to 5 × 104 s−1 using a newly developed shear compression specimen (SCS). The SCS... more
Purpose: This paper deals with the FEA of the sheet metal forming process that involves various nonlinearities. Our objective is to develop a parametric study that can leads mainly to predict accurately the final geometry of the sheet... more
ABSTRACT: In this paper, a Total Lagrangian formulation based on the Logarithmic strains is developed. The variation in these strains is based on the variation of the Engineering strains and the variation of Green strains. The “true”... more
PEM fuel cell assembly pressure is known to cause large strains in the gas diffusion layer (GDL), which results in significant changes in its mechanical, electrical and thermal properties. These changes affect the rates of mass, charge,... more
