In the following picture I have plotted true stress vs plastic strain (colum K vs colum A of the Excel). However, when placing the zero plasticity at yield strength (for fy=260MPa; ep=0), it is like my curve mismatches, (circled in blue). It is not unirform at that point.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/777\/G62UW1G4HB43.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/777\/G62UW1G4HB43.png\" alt=\"image.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-167425","topic","type-topic","status-closed","hentry","topic-tag-plasticity"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["3473"],"_bbp_likes_count":["0"],"_bbp_subscription":["248737"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["167425"],"_bbp_forum_id":["27791"],"_bbp_engagement":["181155","248737"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["208677"],"_bbp_last_active_id":["208677"],"_bbp_last_active_time":["2022-03-17 16:02:49"]},"test":"dariomontesnavagmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/167425","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\/167425\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=167425"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
