Abstract：

The bending springback was studied to find the relationship between forming load and bending stage in sheet metal forming using 1t servo press. The calculating model for full plastic force was created using the conclusion that forming load can change the stressstrain in geometric neutral plane based on Abaqus. The calculating springback is proved to be in good agreement with the experimental ones in full plastic bending,which shows that the formula for calculating the full plastic bending is accurate and reliable.
