I have never done a <strong>thermo-structural coupled analysis<\/strong> to mention it!<\/p>\n<p>I want to simulate a <strong>linear friction welding process<\/strong> in 3D and the following data are available:<\/p>\n<ul>\n<li>Temperature dependent material parameters (thermal conductivity, heat capacity, density, youngs modulus, poission ratio, and some others&#8230;.)<\/li>\n<li>Stress strain diagramm at room temperature<\/li>\n<li>And of course my geometry<\/li>\n<\/ul>\n<p>So here is my question\/issue: I have tried several analysis to simulate this problem (transient thermal with coupled transient structural, coupled field transient)<br \/>But it does not converge or give me any realsitic results&#8230;<\/p>\n<p>To specify -&gt; I want to simulate the whole process which includes the linear motion (I implemented it via a simple sinodal velocity), the generation of heat via the surface contact, and of course the deformation and temperature profile.<\/p>\n<p>So my question would be if it is even possible to solve this problem via a thermo-mechanical coupled analysis? As I mentioned before the &#8220;Coupled Field Transient&#8221; analysis type seems reasonable to solve this problem or did I missunderstood this completly?<\/p>\n<p>And is it better to implement the heat caused by the friction between the two pieces as a simple heat flow as a function of time and temperature, or over the contact itself?<\/p>\n<p>Maybe someone can help me with this problem or give me some advices how to do it and if the suggestions I made are even correct?<\/p>\n<p>I am thankful for everything that helps!<\/p>\n<p>&nbsp;<\/p>\n<p>Greetings, Dominic<\/p>\n","protected":false},"template":"","class_list":["post-290047","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["287898","20905"],"_bbp_author_ip":["23.217.200.71"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["289"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["290047"],"_bbp_forum_id":["27784"],"_bbp_engagement":["20905","287898"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["291142"],"_bbp_last_active_id":["291142"],"_bbp_last_active_time":["2023-07-01 16:04:12"]},"test":"109095fhwn-ac-at"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/290047","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\/290047\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=290047"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
