| Abstract Scope |
Metallic materials often exhibit complex mechanical behaviors such as plastic anisotropy, tension-compression asymmetry, and path-dependent flow stress. For instance, lightweight alloys—including high-strength steels and aluminum alloys—are known to undergo significant anisotropic hardening under changes in loading path. To enhance the fidelity of forming simulations used in process design, accurate constitutive models and their robust numerical implementation are essential. In this talk, recent advances in the development of anisotropic hardening models are presented, with a focus on microstructure-informed approaches for polycrystalline materials, coupled with distortional plasticity. These constitutive models are capable of predicting the evolution of flow stress under various loading histories and serve as effective tools for material design by linking mechanical properties to underlying microstructural characteristics. |
