Research Abstract

For accurate numerical simulation of sheet metal forming, the use of appropriate material models that describe the workhardening, the Bauschinger effect and the anisotropy of sheet metals is of vital importance.
In the present work, material properties at a large strain were determined by the elasto-plasticity inverse approach. For the large strain workhardening characteristic, the weighting parameter in the combined Swift-Voce model was identified from an in-plane cyclic bending experiment. For the determination of the Bauschinger effect, a set of material parameters of the Yoshida-Uemori kinematic hardening model were identified from a three-point cyclic bending experiment. For the anisotropy, the sixth-order polynomial type yield function was proposed, and based on the model, the description of the evolution of anisotropy with increasing plastic strain was presented.
