nonlinear static structural analysis. Apply increasing load in steps & release.

Using Optistruct & Hypermesh non linear static analysis, I wish to apply increasing load in steps and then release the load. I wish to see the residual deformation due to yielding of the structural steel once the applied load has been removed. 

This is not a transient time dependent scenario. I believe DLOAD, TLOAD1, TABLED1 cards may be relevant.

1 - How are Optistruct users best able to learn this loading method? 

2 - where in the support documentation is this covered? This is a fundamental FEA topic.
