Hello ! I would like to ask for help for configuring this simulation in Workbench.
The problem is a contact between a hemi-sphere and a plate in which I want to evaluate stresses and contact radius when a downforce is applied to the hemi-sphere ,to compare to the analytical solution. I am simplifying it to a 2D problem with symmetry.When I have a frictionless model I get Hertzian contact stresses.But when I put friction in it ,instead of JKR ,MG or DMT model , I get again  the Hertzian model .I don’t know how to continue. Here is the result where I get the von Mises stress without  , and with friction applied<\/p>\n

Thank you and Im waiting for your response!<\/p>\n","protected":false},"template":"","class_list":["post-364261","topic","type-topic","status-closed","hentry","topic-tag-2d-axisymmetrical","topic-tag-adhesion-1","topic-tag-contact","topic-tag-frictional-contact-issues","topic-tag-hertz-contact-1","topic-tag-mechanical","topic-tag-mesh","topic-tag-workbench"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
