I attached the .inp file, thanks for your helphttps://files.engineering.com/getfile.aspx?folder=91c299ce-3768-4781-bb93-580509e9cbda&file=7200-kn-2.inp

I only apply a 7200 KN in-plane load to the model. also by using buckle analysis results, I added imperfection to keywords.

Hi I have a model in Abaqus standard, my model is a sandwich panel under in-plane compression and lateral pressure. My Model units are mm, Young’s modulus, and Yield stress in MPa. also, I have Cohesive layer and I used Quads Damage (Damage evolution and Damage stabilization Cohesive is also...

My problem solved. Thanks for your help

I checked your suggestion and used automatic stabilization in step settings. but the error still is. I send my Model for you. can you look at it?https://files.engineering.com/getfile.aspx?folder=68656e58-3369-453a-9fb2-f18d0af92785&file=SPS_Model.rar

I decided to use surface-based cohesive behavior but I can't figure out how to calculate knn, kss and ktt, so I had to use cohesive elements. in interaction module I used coupling constraint. I coupled in all directions and in boundary condition Ux=Uz=UR0. and applied boundary condition to...

Hi everyone I have a model in abaqus standard, my model is a sandwich panel under in-plane compression and lateral pressure. I’ve got this error: Too many attempts made for this increment and this warning: Exhausted the contact constraint pool. Cutting back the time increment and redoing the...
