Lets say I solve a simple test model of 2 circular plates with a 0.2 COF contact between their faces in two different methods. This might represent a friction clutch with one side fixed, which is a known hand solution. <\/p>\n<p>I can solve with an applied rotation (1 degree) of the free side and measure a moment reaction. That moment reaction is presumably the amount of torque that maintains equilibrium. <\/p>\n<p>Solving a separate case where I apply that same measured torque from the previous analysis doesn&#039;t converge (or struggles to). I believe this is expected since I am approaching continuous slip. <\/p>\n<p>So the question is, what about in-between this limiting torque? If I can measure 0.5 degrees of rotation from an applied torque of some value less than my limiting static torque, does that mean the clutch has rotated and then come to rest? Or would this be interpreted as a slipping clutch?<\/p>\n<p><\/p>\n<\/p>\n<p>Thanks for any input on this.<\/p>\n","protected":false},"template":"","class_list":["post-164987","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["463"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["164987"],"_bbp_forum_id":["27791"],"_bbp_engagement":["193","156580"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["200878"],"_bbp_last_active_id":["200878"],"_bbp_last_active_time":["2021-12-23 13:23:00"]},"test":"nds88"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/164987","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\/164987\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=164987"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
