**v6.03.156** SSNP156 — Contact validation benchmark NAFEMS 4: loaded pin
================================================================================

**Summary:**

This problem is the fourth test case of a benchmark NAFEMS for validating touch-friction. The benchmark references are obtained with the Abaqus and MARC codes.

This test models a contact with friction between a pin and a mesh bore with different finnesses and therefore not compatible. However, the calculation with *Code_Aster* requires the use of compatible meshes.

This test includes 2 models to test:


* linear and quadratic elements,


* 'CONTINUE' contact treatment formulations with friction


* contact pressures and tangential frictional forces
