The macroscopic deformation behavior of sheet metals is related physically to the microscopic deformation mechanism. For BCC metal, there have three kinds of slip systems, and the rules of the active slip system still not clear. A program is developed based on the proposed crystalline plasticity dynamic explicit finite element model to simulate sheet metal stamping as well as predict texture evolution. A stable proportion factor has been given to the different slip system and introduced into the rate-independent polycrystalline model. A proper factor has been found by the contrast between the simulation result and experiment data.
