Full‐field optical measurements like digital image correlation or the grid method have
brought a paradigm shift in the experimental mechanics community. While inverse …

For metallic materials, standard uniaxial tensile tests with round bar specimens or flat
specimens only provide accurate equivalent stress–strain curve before diffuse necking …

Lightweight sheet metals are attractive for aerospace and automotive applications due to
their exceptional properties, such as low density and high strength. Sheet metal forming …

This paper reviews the most recent models for description of the anisotropic plastic behavior
and formability of sheet metals. After a brief review of classic isotropic yield functions, recent …

DIC-based identification of the constitutive parameters of an elastoplastic law is addressed
both from a general viewpoint, and applied to the particular case of dog-bone sample made …

Simulation of sheet metal forming requires the flow curve (ie the true stress–strain relation)
over large strains. This paper presents a method for obtaining the flow curve of sheet metals …

Numerical simulations have become essential in engineering and manufacturing processes
involving plasticity. The reliability and effectiveness of the simulations depend strongly on …

The exact stress–strain curve can be directly identified from uniaxial tension experiments up
to the point of onset of diffuse necking. To gain insight into the post-necking hardening …

Micromechanical modeling of material behavior has become an accepted approach to
describe the macroscopic mechanical properties of polycrystalline materials in a …

The virtual fields method is an approach to inversely identify material parameters using full-
field deformation data. In this manuscript, a new set of automatically-defined virtual fields for …
