.. _V6.03.167: **v6.03.167** SSNP167 - Inclusion of two crowns under non-uniform pressure ================================================================================== **Summary:** This test is used to evaluate the performance of Aster in terms of the treatment of contact between two structures with compatibility and geometric incompatibility between the master and slave surfaces under the small disturbance hypothesis. We consider a structure composed of two concentric rings. The interface between the two rings is the contact surface. Their stiffness, represented by their Young's modulus, plays an important role in evaluating the value of deformations and fluctuations in contact pressure. We also want to know what are the effects of using a higher-order mesh, with the use of linear or quadratic meshes. An analytical solution was developed for this problem in order to validate the calculated numerical results. The validation of this test focuses on the values of contact pressure and displacement. .. 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 Mod_lisation_G Mod_lisation_H Synth_se_des_r_sultats
