My goal is to create a similar stress-strain curve in the software with the experimental results that I have. What I did is that I created a Soft Clay material with a Mohr-Coulomb model and after that, I created the cylinder model under triaxial compression but I am not sure if I used enough boundary conditions. I would also like to add that this is nonlinear.&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>The following screenshot is what happens and I can&#8217;t seem to move forward from this.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/09-04-2023-1681041257-Screenshot 2023-04-06 144137.png\" alt=\"\" width=\"990\" height=\"526\"><\/p>\n<p>&nbsp;<\/p>\n<p>I am not sure what data I should show but if anyone can help I am willing to give what is needed for your understanding.&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-278585","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["281414","240"],"_bbp_author_ip":["23.44.170.61"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["558"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["278585"],"_bbp_forum_id":["27789"],"_bbp_engagement":["240","281414"],"_bbp_voice_count":["2"],"_bbp_reply_count":["12"],"_bbp_last_reply_id":["279037"],"_bbp_last_active_id":["279037"],"_bbp_last_active_time":["2023-04-12 12:30:45"]},"test":"jsdelacruz14up-edu-ph"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/278585","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\/278585\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=278585"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
