Load step for quasi static analysis

Hello everybody!

 

I am new to hyperworks and trying to simulate an autofrettage process (a stempel which is pushed through a tube). What I need is the final state and plastic deformation after the process.

Usually I would create two load collectors for the constraints and loads and then implement a load step (e.g. for a static analysis).

How can I define that the stempel is moving/pushed through the tube instead of an acting force as load definition?

 

I am also struggling with finding the proper material card for the plastic deformation.

 

I would really appreciate any help or advice :-)

 

Cheers
