报告摘要：
Emerging structural metals show complex mechanical behavior due to their microstructural complications. The particular complex responses include high anisotropy, non-linearity, and asymmetry in the stress-strain responses. For example, advanced high strength steels (AHSS) show significant anisotropic and asymmetric behavior under strain path changes, and magnesium alloys have strong strength differential between tension and compression. For accurate descriptions of the complex material behavior, advanced constitutive models and corresponding numerical technique have been developed and applied to process optimization for better product quality. In parallel with advanced simulation technologies, novel experimental techniques characterizing this complexity in mechanical responses of materials have been devised. The novel mechanical test methods represent multi-axial and non-proportional characteristics of corresponding material models. In this talk, recent trends of constitutive modeling and FE simulations in the field of material science and manufacturing will be briefly introduced. Then, more details on the constitutive modeling procedure to capture complex anisotropic and nonlinear mechanical behaviors of steels will be provided.
