Comparison of two models for anisotropic hardening evolution in metals during complex loading
Source abstract
Abstract
In this work, two models for anisotropy and hardening development in sheet metals during forming processes involving loading path changes are formulated and compared. In particular, such development is due to the formation and interaction of dislocation microstructures in the material, resulting in an evolution in the size, center and shape of the yield surface. Such yield surface evolution is accounted for in the current models with the help of evolving structure tensors. After briefly reviewing the formulation of each model, attention is focused in the current work on parameter identification and a comparison of the two models in the context of their application to forming processes.
