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 defined for this)
My step is riks. the maximum number of increments is 1000, initial increment size=0.01, minimum 1e-15 and maximum is 1.0
In the Interaction module, I used surface to surface contact for between cohesive and top layer and the core layer. and coupling constraint is shown in the below figure.
in the Load module, My load is 7200kn, and the boundary condition is shown in the below figure.
I've got this error:
"A zero displacement solution was found in the first iteration of a riks step. The analysis cannot proceed. The most likely cause is that all displacement degrees-of-freedom are constrained to be zero."
I've check units and property of cohesive layer but I can't find anything wrong, and my boundary Condition is according to My reference.
