Hello,
I'm using the hex solid elements in the simulation of composite delamination. 3D solid instead of beam or shell elements are chosen in order to take advantage of the crack band model. However, I was wondering if solid elements in MARS has the large deformation formulation. The MRAS manual only mentioned Ten-Node Large Deformation Element while no detailed information were provided for other elements. The figure I uploaded shows one simulation I did with FBSingleIP 8-node hex elements, but I'm not sure if the results are accurate. Does anyone have any experience? Thanks.
Best,
Weixin
