You can use finite element method to analyse problem because it is nonlinear problem . You can't use the analytical method to solve this problem.

You will check working condition before select materials. I think polyurethane have a good properties and it is the first choice for me.

Hello aorsi
If you want hexahedral mesh in your model I thing you must use other program for meshing such as Altair hypermesh and you can import your model to abaqus program after meshing fineshed. orther way using quad tet element in abaqus that its effect of quad tet is reduced element...
You 're correct. Shear locking is the numerical problem . You can found it in the first order element and you can use higer order element , mesh refinement ,reduce integration point in element to solve shear locking. Good luck .

I am abaqus user. In abaqus i have used coupling constraint to descript the kenematic or distribution force on section . Have coupling constraint in Ansys?.

you can study in user manual of program (getting start ) and general finite element method book (J.T Reddy and R.D. Cook are introduced (Finite element analysis))
thank you
