The geometry is shown in Figure 1. (The experimental study is done by Kirk and Sanford).<\/p>\n<p>The material is polypropylene (PP). For the elastic perfectly plastic model, Bilinear Kinematic Hardening was used with Tangent Modulus of 0. Could you please check and see if there is any mistake in the material data. The material data is shown in Figure 2. <\/p>\n<p>The fracture is modelled using Pre-Mesh Cracked. <\/p>\n<p>My goal is to find the plastic zone shape and size and compare it with Irwin&#039; plastic zone. <\/p>\n<p>For the shape I am using isolines (shown in Figure 3 &#8211; equivalent elastic strain) but how could I determine which one is the plastic zone and how do I extract\/know the length of plastic zone? <\/p>\n<p><\/p>\n<\/p>\n<p>Sincerely,<\/p>\n<p>aimeri42<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/G0I8JIN9YNIW\/geometry-jpg.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/G0I8JIN9YNIW\/geometry-jpg.jpg\" alt=\"geometry.JPG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-50568","topic","type-topic","status-closed","hentry","topic-tag-elastic-plastic","topic-tag-elastic-plastic-material","topic-tag-plasticity","topic-tag-stress-intensity-factor","topic-tag-structure"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["22820"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["????"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1838"],"_bbp_subscription":["249122"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["50568"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","174922"],"_bbp_voice_count":["2"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["136068"],"_bbp_last_active_id":["136068"],"_bbp_last_active_time":["2020-12-15 00:28:09"]},"test":"664c0f3a7deb4d1ee45e6567a90a9dfc723a63a2"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/50568","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\/50568\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=50568"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
