In experiment, the composite plate is held on a foam like material, under the influence of gravity only and its one corner is displaced by a very fine loading curve. While simulating, I was confused about&#8230;&lt;br&gt;1. Should I model the lower foam like material too (or is there any other way around)&lt;br&gt;2. What will be the approprite boundary condition for the plate to keep it resting like that (as in the experiment)&lt;br&gt;3. Any other helpful advice will be appreciated :)&lt;br&gt;&lt;br&gt;Thanks for your time.&lt;br&gt;Have a great day!&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-442800","topic","type-topic","status-publish","hentry","topic-tag-compositematerials-1","topic-tag-ansys-ls-dyna-1","topic-tag-ls-dyna","topic-tag-ls-prepost"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27814"],"_bbp_topic_id":["442800"],"_bbp_author_ip":["210.94.210.205"],"_bbp_last_reply_id":["442845"],"_bbp_last_active_id":["442845"],"_bbp_last_active_time":["2025-10-02 06:12:05"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["602729","58821"],"_btv_view_count":["164"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["58821"]},"test":"mhaseebdgu-ac-kr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/442800","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\/442800\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=442800"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
