Need help: Consideration of ply failure in Hyperworks/OptiStruct

Hello everyone,

I have a problem in Hyperworks OptiStruct. It concerns a 3-point bending test of a CFRP sandwich panel.

I move the load applicator onto the plate at a constant speed and then want a plot of the force-displacement diagram in HyperGraph as a result.

Unfortunately, the failure of the individual plys is not taken into account and the course of the diagram is linear over the entire range. However, there should be drops somewhere due to failure...

I can also send you more information and the corresponding file.

I am grateful for any help.
Many thanks in advance.
