Translations:FEM Shear of a Composite Block/37/en

From the result it is clear that the core remains largely undeformed and helps to resist the deformation of the soft matrix (compare the shear angle of the blue colored part to that of the green colored part). What it also highlights though is that under Simple Shear conditions the faces of the composite block do warp, implying that the sliding boundary condition at the base of the cube does provide an undue constraint.
