Dear Respected Researchers,
I am trying to model a frictionless contact of flexible-flexible cylindrical surfaces.
First surface is hyper-elastic and second surface is elastic material. How can I model this contact problem with FEM matlab code?
Thanks in advance for your reply,
if you are using ansys software, model hyperelastic material by mooney-Rivlin constants and metal by E,nu with stress-strain curve. Add flexible contact at interface without supplying friction. Understanding the physics of deformations, at one node of both material displacement will be coupled to avoid rigid body displacement.
Understanding the physics of deformation means understanding the hertzian contact in this area which is a line contact then use the hertzian contact to calculate you shear and normal stresses, afterward you can use Ansys to model your surface geometry.
Thank you very much for your answers.
I modeled my contact problem in abaqus software. It is nonlinear because of hyper-elastic material and contact problem. It converges hardly.
