Nonlinear cyclic analysis and hysteretic loop by Ansys APDL

Nonlinear cyclic analysis and hysteretic loop by Ansys APDL

Nonlinear cyclic analysis and hysteretic loop by Ansys APDL

(OP)
Hello

in Ansys APDL. I have a plane 183 element that is 100x50 m in size. subjected to a harmonic displacement at three different edges (the left, right, and bottom). These edges are constrained in the vertical direction.
The analysis type: Transient, with steps 0.02
Using a linear material, I have got a cyclic response (for point A, for example). However, when I use a nonlinear model (TB,BISO) the analysis stops (I have tried different models and got the same). and I can not get any plastic strain as well
I want to show the hysteretic loop for this problem.
My questions:
1. Why does the analysis stop when using the nonlinear material? and the strain is just elastic? no plastic strain!
2. How can I plot the hysteretic loops?

Thanks
