First and foremost, I need to ask if using the the multilinear model is the correct choice, considering the little plastic strain that the material suffered. Second of all, I get the warning on picture 2 after a while, which means the amount of points I&#8217;ve put in the multilinear model are not enough. Taking into account that I&#8217;m performing a tensile test, I&#8217;m simply inducing a displacement, so there is a chance I go over the plastic limits from the stress-strain curve. May I just ignore the warning or do I need to put more points in the table?<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/28-08-2023-1693237122-Screenshot 2023-08-28 004125.png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/28-08-2023-1693237157-Screenshot 2023-08-28 004321.png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-303683","topic","type-topic","status-closed","hentry","topic-tag-Multilinearisotropichardeningmodel-1","topic-tag-plasticity"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["18369","275204"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1997"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["303683"],"_bbp_forum_id":["27815"],"_bbp_engagement":["18369","275204"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["303702"],"_bbp_last_active_id":["303702"],"_bbp_last_active_time":["2023-08-28 17:13:18"]},"test":"up202102717up-pt"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/303683","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\/303683\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=303683"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
