I am performing a 3D analysis.<\/p>\n<p>Initially, I had not modeled the blue part, and considered only the orange one with a defined ring-area on its back, to which I applied fixed support. That doesn&#8217;t seem to work great, as the stresses in the support region are artificially high and would get higher as I refined the mesh.<\/p>\n<p>Second approach was modeling the blue part, set it up as a rigid body and fix it with a body-ground joint. Then, I applied bonded contact between the parts (they will indeed be glued together eventually). The problem with the artificially high stresses seems to persist.<\/p>\n<p>Lastly, I&#8217;ve set the contact as frictional. The max stress value has lowered, but I am still not sure what is the best way to proceed with this kind of simulation.<\/p>\n<p>Could anyone please share some insights on how you would set it up?<\/p>\n<p>Thanks in advance,<br \/>Henrique<\/p>\n","protected":false},"template":"","class_list":["post-248323","topic","type-topic","status-closed","hentry","topic-tag-contact","topic-tag-mechanical","topic-tag-rigid-body"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["254589","58821","240"],"_bbp_author_ip":["23.220.96.180"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["2594"],"_bbp_status":["publish"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["248323"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","58821","254589"],"_bbp_voice_count":["3"],"_bbp_reply_count":["13"],"_bbp_last_reply_id":["252831"],"_bbp_last_active_id":["252831"],"_bbp_last_active_time":["2023-03-07 11:37:38"]},"test":"henrique-geraissatedesy-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/248323","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\/248323\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=248323"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
