Purely plastic analysis

Purely plastic analysis

Purely plastic analysis

(OP)
Hi guys,

I'm trying to proceed a fully plastic analysis (without elastic behavior) of a plate under axial load.

In order to do a fully plastic analysis, I adopted a very high Young's modulus (i.e. 10^10 MPa, because it's not possible to remove the elastic part) and run a general static step.

The fact is that I'm not getting a proper answer. It is requiring now a significant amount of damping in order to stabilize the analysis, which is affecting the response.

Does anyone know another way to do a fully plastic analysis (disregarding the elastic behavior)?

RE: Purely plastic analysis

If you are having large deformation you may want to try explicit step. A little more description of your set up and maybe a picture may be helpful. But I do not know how to solve this I am relatively new to abaqus.
