This means that the static structural simulation shouldnt go past yield point right?nWith multilinear plasticity model, does it mean that the original yield point has already been exceeded? I&#8217;m not too sure what multilinear means?nI have been tasked to validate my real-life experiments by using a material property that has not and would not exceed yield point but bilinear plasticity model does not seem to produce great results that multilinear does. However, i cannot justify the use of multilinear either as i do not understand its theory.nHope to hear from someone soon.nThank you (:n<\/p>\n","protected":false},"template":"","class_list":["post-50965","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["23219"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["???l"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["5933"],"_bbp_subscription":["254075"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["50965"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","179965"],"_bbp_voice_count":["2"],"_bbp_reply_count":["33"],"_bbp_last_reply_id":["138256"],"_bbp_last_active_id":["138256"],"_bbp_last_active_time":["2021-01-10 16:48:04"]},"test":"yappyap"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/50965","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\/50965\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=50965"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
