I modeled the plasticity using a multi linear Kinematic hardening model with 6 stress-strain points. The Hysteresis graph (Shear Force in the beam vs Beam Rotation) , as shown below ,is very different from the experimental one. why is the graph not expanding as the experiment? Should I use Chaboche model with Isotopic Hardening to get accurate results? The material Models are correct since they give fairly good results under monotonic loading with Isotropic hardening. If I have to use the chaboche+Isotropic model can you please explain how to model them?<\/p>\n<p>Thanks<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/G6RBF7BD5X9R\/capture-3-png.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/G6RBF7BD5X9R\/capture-3-png.png\" alt=\"Capture 3.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-47620","topic","type-topic","status-closed","hentry","topic-tag-chaboche","topic-tag-kinematic-hardening","topic-tag-material-models","topic-tag-plasticity","topic-tag-structural-mechanics"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["19822"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["\u015cGQ"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1707"],"_bbp_subscription":["251899"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["47620"],"_bbp_forum_id":["27791"],"_bbp_engagement":["88","174985","177760"],"_bbp_voice_count":["3"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["133468"],"_bbp_last_active_id":["133468"],"_bbp_last_active_time":["2020-11-18 03:04:51"]},"test":"abelberhanemeskel"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/47620","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\/47620\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=47620"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
