I would like to ask for help for configuring this simulation in Workbench. <br \/>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 &nbsp;the Hertzian model .I don&#8217;t know how to continue. Here is the result where I get the von Mises stress without &nbsp;, and with friction applied<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/25-04-2024-1714058260-mceclip1.png\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/25-04-2024-1714058228-mceclip0.png\"><\/p>\n<p>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":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["343591","99"],"_bbp_author_ip":["23.52.43.16"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["929"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["364261"],"_bbp_forum_id":["27791"],"_bbp_engagement":["99","343591"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["369578"],"_bbp_last_active_id":["369578"],"_bbp_last_active_time":["2024-06-03 13:21:41"]},"test":"up1072444ac-upatras-gr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/364261","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/364261\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=364261"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
