My goal is to validate analytical membrane and bending strain calculations that I did. But without a working simulation this is not possible. <\/p>\n<p>The problem is that my simulation won&#039;t converge for the displacements that I apply at the plate. I am using a material model with a stress-strain curve up to 100% strain. The displacements are applied by imposing a constraint on every node into x-y-z direction. These displacements are applied over 10 seconds. And should give the desired shape. However, the simulation does not converge at a certain point. <\/p>\n<p>I am using the arclength method to solve the simulation and large deflection is turned on. <\/p>\n<p>The nodal constraints are applied with an APDL which gives the nodal displacement in every direction, I don&#039;t have any other boundary conditions applied. Underneath you can see the mesh that I am using, the dimension of the plate are approx. 4500x500mm with 12mm thickness. <\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/M4OL54GBFX7W\/mesh-png.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/M4OL54GBFX7W\/mesh-png.png\" alt=\"mesh.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-51357","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["23621"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["?^\u0006a"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["258"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["51357"],"_bbp_forum_id":["27791"],"_bbp_engagement":["88","185170"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["139259"],"_bbp_last_active_id":["139259"],"_bbp_last_active_time":["2021-01-18 22:36:16"]},"test":"jvancappellen"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/51357","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\/51357\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=51357"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
