Because I am intersted also in plastic behaviour, if I use 1090 MPa component will be stiffer and material does not yield and if I use 233 MPa material will deformate more than real application (probably, because is a bending like analisys).nCould Ansys manage non linear elastic behaviour like displayed one?.Thanks and excuse for my english.n<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/178\/DJ33BUR65C2V.jpg\" width=\"\" height=\"\" \/>n<\/p>\n","protected":false},"template":"","class_list":["post-54502","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["26835"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["M]?S"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["1"],"_btv_view_count":["2890"],"_bbp_subscription":["256392"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["54502"],"_bbp_forum_id":["27815"],"_bbp_engagement":["240","182258","185297"],"_bbp_voice_count":["3"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["150639"],"_bbp_last_active_id":["150639"],"_bbp_last_active_time":["2021-04-24 10:43:43"]},"test":"andreamadonia"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/54502","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\/54502\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=54502"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
