I only have biaxial test data. Here, I put the test data including lateral strain. Further I am curve fitting it to find the respective constants for the material model. The problem is that when I see the curve as shown in figure below. The curve is plotted for stress (m m^-1) and strain (C). The units are wrong. Can anyone help me what it is trying to represent or is there something wrong with my setup?<\/p>\n<p>Thanks in Advance<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/849\/TVYG5GCD1B8Q.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/849\/TVYG5GCD1B8Q.png\" alt=\"image.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-158643","topic","type-topic","status-closed","hentry","topic-tag-curve-fit","topic-tag-hyperelastic"],"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":["1864"],"_bbp_likes_count":["0"],"_bbp_subscription":["232313"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["158643"],"_bbp_forum_id":["27791"],"_bbp_engagement":["897","185297","185782"],"_bbp_voice_count":["3"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["179243"],"_bbp_last_active_id":["179243"],"_bbp_last_active_time":["2021-05-25 07:18:24"]},"test":"abhinav_tiwari"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/158643","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\/158643\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=158643"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
