Thanks for your answer. I'm validating LaRC05 criteria so I'm unfortunately stuck on Abaqus/Standard. Most definitely convergence issue comes from contact between 12 layers in my model and I'll have to check if the interlaminar properties affect the results in any way.
I'm inspecting...
I'm doing an Abaqus/Standard model verification for a 3D composite coupon using C3D8R elements and LaRC05 failure criteria (Load-displacement curve).
Interlaminar properties are defined using cohesive interaction property and General contact interaction type.
When running my simulation the...
I calculated equivalent elastic properties of a honeycomb core using analytical Ashby & Gibson approach.
Material was defined using "Engineering Constants" submenu in elastic material properties section (with analitically calculated values).
After that I defined material orientation using local...
