I would like to radially fasten 2 rings together using an interference fit, and then utilize a bolted joint to prevent any axial movement of the rings.<\/p>\n<p>I have geometrically modelled the interference fit. Timestep 1 allows it to resolve. I&#039;ve loaded and then locked the bolted connection (via beam element) in timestep 2 and 3. In timestep 4, I put the rings under a rotating velocity.<\/p>\n<p>In real manufacturing, the rings would be assembled and then the bolted joints would be drilled and tapped after the interference fit (shrink) resolves itself. However I&#039;m struggling to model it in that way as I cannot suppress the beam element for timestep 1. <\/p>\n<p>Since the interference fit displaces both bodies, the beam element imposes a large compressive force on both rings as a result of its response to shear. This seems to artificially inflate the stresses in those areas. <\/p>\n<p>Is there a combination of settings I could use in the Contacts tool to avoid this artificial inflation? The perfect solution would be to somehow model the hole after the interference fit resolved, but I&#039;m not sure of a way to do that.<\/p>\n<p>Thanks<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/227\/FZT0NJN1CXA0.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/227\/FZT0NJN1CXA0.png\" alt=\"RRProblem.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-159689","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":["1326"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["159689"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","205711"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["182871"],"_bbp_last_active_id":["182871"],"_bbp_last_active_time":["2021-06-22 15:00:47"]},"test":"sclineemeassociates-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/159689","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\/159689\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=159689"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
