Is there any failure mode you suggest in that case?
The material is 3D-printed resin.The model have fixed support at the bottom surface with displacement on the top surface to simulate quasi-static compression.
Or should I use ERESX, NO after include plasticity model in the material?
Or should I just pinpoint the strain at which the stress go beyond the yield strength? 
Sorry if the questions are too much.
Thank you in advance.
