Hello all,

i try to simulate an microstructure of two different materials (with different stiffness). Two sides of the model are fixed and in one direction a displacement is applied (look for picture). My problem is, that the upper side don’t deform planar, because of the different stiffness from the materials. But i need this planar deformation. So how can I realize this in PATRAN?

Thanks
