Hello, community!

I am simulating elasto-plastic response of composite material in Abaqus. Possible plasticity onset in matrix is accounted for with Concrete damaged plasticity properties.

After applying significant compression or tension strain (even 10%) to the whole model, PEEQ strains in Visualization are shown as Zero in the matrix region. I checked stresses in the matrix region - they are more then those specified in both Compression and Tension Behaviour. Meanwhile, applying shear strain to the same model gives PEEQmax=0,3.

I would be very thankful, if someone will give me a good idea of the problem
