Introduction

In this tutorial we analyze the shear deformation of a composite block consisting of a stiff core embedded in a soft matrix. It demonstrates the use of BooleanFragments and CompoundFilter to create solids for the block and the matrix from two concentric cubes. This work-flow ensures that separate MeshRegions, Materials and Boundary Conditions can be defined for the block and the surrounding matrix. The CalculiX results clearly show the effect of the stiff core on the response of the composite block.
