Meshing Parameters
Use Coarse mesh with element size 0.3106 in.
Material Model
Linear elastic isotropic.
Material Properties
Modulus of elasticity = 3 X 107 psi, Poisson's ratio = 0.
Restraints and Loads
The back face of the larger cube is fixed. Right and bottom faces of the two cubes are prevented from moving in their normal directions. A pressure is applied incrementally on the free face of the smaller cube according to the following time curve:

Results
Use a deformation scale factor of 1.0 to plot results on the deformed shape. Animate the results to see how the two cubes move together after contact.
The linear theoretical elastic maximum displacement is calculated as U = PL1/(A1E1) + PL2/(A2E2), where the subscripts refer to cubes 1 and 2. L is the length, A is the area (A=L2) and E is the Modulus of elasticity.
