Non Linear analysis of a Ring
Non Linear analysis of a Ring
(OP)
I am relatively new to Ansys non linear analysis. Here I have a problem where I need help to model and solve in Ansys. There is a big ring with 4 m OD and 3.5 m ID with a thickness of 0.4 m. on this ring I want to create a permanent deformation of around 50 mm by compressing at diametrically opposite points. I tried defining non linear material but still could not produce any "equivalent plastic strain" with any load.
I am using Ansys Workbench 11. Can some one please help me to define a non linear material properly and do the appropriate analysis settings?

For steel, the simplest option would be to add Bilinear Isotropic Hardening to the material, insert the yield and a tangent.
