Simulation Study of Stamping and Springing Based on Mixted Arithmetic

The paper analyzes the algorithms of numerical simulation.A conclusion that it is suitable to simulate the process of the sheet metal forming by ABAQUS/explicit but it is better to simulate the process of springback using ABAQUS/standard,which is also called mixture arithmetic.The paper also studies the key techniques which concludes cell choosing,meshing and punch dummy velocity.Meanwhile,the multi-angular bending piece is simulated the processes of bending and springback by the mixture arithmetic in ABAQUS,which is valuable to design model.
