Abstract：
|
|
A finite element model has been used to analysis the oil pan forming by the FE software, MARC. The underlying formulation is based on Updated Lagrangian elastoplastic materials model. Von Mises stress, plastic strain, contact friction force and thickness distribution in the workpiece during forming are arrived. Material plastic forming law during forming is revealed and the possible breakage region is forecasted. Therefore the effective analytical method can be provided for design of forming process.
