Test Case
An axisymmetric rubber plate made of Neo-Hookean material is modeled with radius R and height H. The model is subjected to cyclic displacement loading on the top surface. The axial stress obtained at different load steps is compared against the reference solution.
This problem is also presented in VM268
in the Mechanical APDL Verification Manual.
