I am primarily looking at the plastic strains developed in the model, and check whether they are acceptable for the particular material. I am also looking at the stress distributions&nbsp;at the base of the snap fit and check if those would be close to the bending stress value that could be derived from hand calculations using beam theory. I had 3 options in mind:<\/p>\n<p><\/p>\n<p>1) Static structural study with a fixed displacement of the snap fit equal to that of the depth of the over-hang. I&nbsp; do not plan to include the housing so as to not include contact non-linearity.&nbsp;<\/p>\n<p><\/p>\n<p>2) Static structural study, but with contact formulation of the snap-fit and the housing, so that I just have to give a displacement boundary condition at the base of the snap fit.<\/p>\n<p><\/p>\n<p>3) Dynamic analysis<\/p>\n<p><\/p>\n<p>I wanted to know which approach would be the best, and how to justify using it. I think the first approach would be the best and the easiest to do and should give reasonable results.&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-37998","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["10176"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1096"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["37998"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","165012","290587"],"_bbp_voice_count":["3"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["295955"],"_bbp_last_active_id":["295955"],"_bbp_last_active_time":["2023-08-01 16:13:36"]},"test":"omkar5990"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/37998","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\/37998\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=37998"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
