Hot forming theory and simulation methods of automobile load-bearing parts involving with lightweight manufacture have being widely paid close attention to researcher and engineer in the world. The present project focuses on the research of formability and manufacturability of auto body load-bearing parts with hot formed by HSS, and optimization design of the parts based on crash safety. Main research issues include: experiments and analysis of phase transformation and hardness of the load-bearing parts, constitutive models of multi mechanical field coupling, FEA algorithms of elastic-viscoplasticity involving with thermo-mechanics and phase transformation and thermo contact on boundaries, and so on.
