**v6.03.502** SSNP502 - Crush of a polyurethane ring between two non-deformable plates with friction
===============================================================================================================

**Summary:**

The test consists in simulating the crushing under plane stresses of a circular elastic polyurethane ring by two symmetric, non-deformable plates. The objective is to test the functionalities related to contact. This test involves gluing over a contact zone of considerable length with the presence of large elastic deformations.

A symmetric imposed displacement is applied to the two plates; the resultant force as well as the contact pressure for various points in contact are compared with the results obtained in the reference article.

In the three proposed models, the ring is modeled with QUAD4en plane constrained cells:


* **modeling B**, a contact **with friction** treated with the penalization method has been defined between the plate and the ring,


* **modeling C**, a contact **with friction** treated with the continuous method has been defined between the plate and the ring.
