“…C and L have a structure, which is consistent with the macroscopic symmetry of the material. Finally, when yield is defined conventionally with an offset strain of a fraction of a percent, it leads to yield surface shapes in agreement with experiments [10,11]. Under the isotropic hardening assumption, the yield surface only expands because it is controlled by one parameter, the reference stress σ R or, equivalently, the effective strain, ϕ .…”

Abstract. Continuum constitutive descriptions of plasticity suitable for finite element simulations of sheet forming processes are succinctly discussed in this presentation. Although multi-scale approaches allow for a more explicit representation of the physical deformation mechanisms occurring at microscopic scales, they are usually not suitable for industrial applications because of the quick turnaround time needed for process design simulations. Therefore, advances in classical concepts such as plastic anisotropy and strain hardening are still very much in demand. Actual forming simulation examples conducted for the steel industry are presented for illustration purposes.

“…1a is a schematic diagram of biaxial compression tests using adhesively bonded sheet laminate specimens, showing how different stress states can be obtained in the p-plane. Tozawa (1978) investigated the work hardening behavior of both annealed and prestrained sheet metals using the biaxial compression test shown in Fig. 1a.…”

“…Biaxial compression tests are effective in observing yielding behavior in the π-plane [191,204,272]. One of the disadvantages of the biaxial compression test is the difficulty in obtaining accurate stress-strain relations because of friction between the specimen and tool.…”

This paper presents synthetically the most recent models for description of the anisotropic plastic behavior. The first section gives an overview of the classical models. Further, the discussion is focused on the anisotropic formulations developed on the basis of the theories of linear transformations and tensor representations, respectively. Those models are applied to different types of materials: body centered, faced centered and hexagonalclose packed metals. A brief review of the experimental methods used for characterizing and modeling the anisotropic plastic behavior of metallic sheets and tubes under biaxial loading is presented together with the models and methods developed for predicting and establishing the limit strains. The capabilities of some commercial programs specially designed for the computation of forming limit curves (FLC) are also analyzed.
