This problem simulates shear on a cube with dimensions 1 x 1 x 1. Boundary conditions are zero displacement in the X- and Y-direction for nodes at Y = 0, and zero displacement in the Z-direction for nodes at Z = 0.

The shear is simulated by displacing the nodes at Y = 1 in the X-direction by a distance of 1 unit and preventing any displacement in the Y-direction for these nodes. The nodes are then returned to their original position to simulate one cycle of shear deformation.
