Hello first of all I am bending a steel pipe using Abaqus by rotating the bending die ( picture attached ). (the bending die is the circular instance )

When I rotate the bending die it appears strains on it , eventhough I increase Young modulus.

how can I rotate the bending die easily without creating strains in it ?

And I don't want to set the bending die as a rigid body because I want to evaluate the strains That the pipe can include in it.

I have used kinematic coupling.

Bending die = the circular instance
