Simulation of a local compression test in Abaqus
 

Hello, I have already been able to simulate a compression test over the entire surface with my model in Abaqus and the test data fits.

Now I would like to simulate an indentation (local) compression test, but my simulation terminates prematurely.

I am using a self-created and validated HyperFoam material model and the iterative solver as I have non-linear deformation properties and large deformations. I also tried to do the contact definition in the initial step via self-contact (default), but this is not possible due to my discrete rigid stamp, so I currently used the Abaqus function "Contact Pairs".

I use C3D8R as the element of my rectangular body. My bottom side is fixed in U3=0, and I transfer the forced deformation via my reference point (RP) with U3=12.

I would be grateful for any suggestions, regards.
