In Order to better represent the behaviour of concrete I am trying to use the Menetrey- Willam and Drucker Preger model base on the given data (uniaxial compression and young modulus) But when ever I use these two models I face convergence issue which I noticed is at the point where most probably yielding occurs. I derived parameters of both these models based on literature and comparing these with ansys requirements which are fine but still I am having the issue. Additionally, I tried with only Menetrey and Drucker base without any softening behavior still the same problem I am facing. The input of both these models are shown in snap attached. Anyone have idea or experience please share.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/202\/2QFRHI4PT0IF.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/202\/2QFRHI4PT0IF.jpg\" alt=\"Menetrey-willam.jpg\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-164584","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["898"],"_bbp_likes_count":["0"],"_bbp_subscription":["239140"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["164584"],"_bbp_forum_id":["27791"],"_bbp_engagement":["99","199977"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["199595"],"_bbp_last_active_id":["199595"],"_bbp_last_active_time":["2021-12-09 16:50:05"]},"test":"mereenhussainbalochgmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/164584","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\/164584\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=164584"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
