Spring back process in Abaqus

In this example we intend to simulate the spring back process in the Abaqus software

As you know, After the completion of the deep drawing process, due to the spring back phenomenon, the sheet deviates from its desired shape and loses its desired shape, and a slight deviation occurs in the sheet

In this question , we use one Static Step in order to stimulate the spring back process and during this step , the sheet is separated from the other parts and stands freely in the ambit

In this question , we intend to calculate the contour of stress before and after the Spring back process

As you observe the quantities of stress have diminished caused by Spring back phenomenon

In the right picture , residual stress can be observed
