[s281303]

I am analysing a composite plate subjected to pressure on the upper face and constrained at the short sides.
I would like to obtain the von Mises sigma results for the isotropic material at the centre of the layout, but I am unable to do so. I have set the correct number of integration point parameters and I obtain the stress for the other layers, but not for that one.

PS: in the model i'm using PART_COMPOSITE and two different materials: 001_ELASTIC and 054_ENHANCED_COMPOSITE_DAMAGE.

Layers have differents thickness, 0.2 mm composite skin and 5 mm the mat_elastic
