Hi Omer,

Do you use a plasticity model? If you dont the displacements are elastic. If you do, the displacements may result from both elastic and plastic deformation depending to the spot on the structure. You can understand that from the plastic and elastic strain contours.

If your displacement curve after variation back to the Initial value, it means the model has elastic displacement and if displacement after a time get stable in another value, it means plastic displacement.

Hi Dimitris Dimitriou

Thank you for reply.

I use a plasticity model.

I saw countours on deformed shape(u) but I dont understand elastic or plastic.

Because there are only red, yellow and blue countours on wall.

hi Seyed Reza Jafari ,

I investigated displacement time curve.

I have a load time history with 10000 data. Each time step is 0.0001

Therefore displacement doesn't back to initial value. Abaqus analysis have a displacement on each step time.

I know that your model is simulated during 1 sec with 0.0001 tie step. Now, if your model's displacement curve does not back to the initial value, and it means the model has a plastic behavior (in blast or impact test may not has a stable value, but under bending load maybe after a deflection, deflection reach a stable value, which this stable value also means plastic mode).

Thank you for reply. I know what you told . I found that how I will found plastic deformation in ABAQUS. I saw deformed shape of structure. There is permanent deformation in results of analysis. I found it easily with what you told me . Thank you for your help.
