Greetings!

Background: I am attempting to model a multi step analysis, wherein the first step is a quasi static deep rolling process on a shaft with a crosshole (which is visible in the centre) carried out on ABAQUS explicit. (Picture attached) The second step deals with the cyclic relaxation of residual stresses caused by 20 fully-reversed cycles from torque. I intend to carry out the second step as an implicit analysis on ABAQUS standard.

Current state: I got the import smoothly into standard sing the predefined initial state, and I see some springback and stress redistribution occurring.

Question: When I apply a torsional load on a reference point at one end of the specimen in the ABAQUS standard step, there is no displacement, reaction or stresses. There is springback occuring in the deep rolled region however. Am I doing something wrong?

Any help is appreciated. Thank you.
