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
