Automobile safety, energy conservation and environmental protection has become the vehicle of the three major areas of work has important social and economic significance of research hot. Automobile collisions safety is very important basic attributes; in many countries all listed vehicle collisions must meet stringent safety regulations; it is also an important indicator of consumer concern and the key products of vehicle companies expand the market. Automobile safety falls into two categories, active safety and passive safety. Body of research into the structure of anti-collision vehicle passive safety is the main element of the study, which directly affects the target of the vehicle passive safety. In the research of passive safety in vehicle collision simulation technology in the last 20 years have developed rapidly in the vehicle development process and play a tremendous role, despite the computer simulation can not replace expensive collision tests, but it has advantages as an inevitable trend in the vehicle collision safety study. Therefore, how to ensure the simulation precision and accuracy is crucial to engineering applications. Further improve the automated theory, and continually enhance the accuracy of simulated body structure is the focus of research on anti-collision simulation. Material models do not seriously affect the precision is an important factor in the collision simulation accuracy. In reference to auto body parts, manufacturing, painting dressing and other processes will impact the material itself. Is the former materials model for stamping, painting dressing still applicable to the latter material for stamping, painting dressing? If those former materials model apply to stamping, painting dressing no longer applies to the latter material, what should be considered about material mechanics performance after stamping, painting dressing in material models correctly? These issues pose a challenge to the reliability of material models in analysis of vehicle collisions.It is against this background that this proposed research in material shaping
