.. _V6.03.154: **v6.03.154** SSNP154 — NAFEMS contact validation benchmark 1: cylinder roller contact ============================================================================================= **Summary:** This problem is the first 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 Hertz contact with and without friction between a solid and a cylinder of different stiffness meshed with different fineness. An analytical solution exists for the frictionless case. This test includes 6 models to test: * linear and quadratic elements, * the 'CONTINUE' contact treatment formulations without and with friction. * 'DISCRETE' frictionless contact treatment formulations .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Probl_me_de_r_f_rence Solution_de_r_f_rence Mod_lisation_A Mod_lisation_B Mod_lisation_C Mod_lisation_D Mod_lisation_E Mod_lisation_F Synth_se_des_r_sultats
