I am using an explicit dynamics study. Whenever I run the analysis, the dropped weight tears through the pad and bounces off of the ground. I am guessing this could be due to incorrectly defining material properties.<\/p>\n<p>I defined my own material based on some known properties. If there are any obvious errors I made as far as what properties I chose to define the material, help would be appreciated. I attached screenshots of my current material properties, and a single frame of the final results.<\/p>\n<p>Thank you.<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/12\/12-12-2022-1670860895-Screenshot 2022-12-12 095526.jpg\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/12\/12-12-2022-1670860916-Screenshot 2022-12-12 095734.jpg\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-243798","topic","type-topic","status-closed","hentry","topic-tag-acp-explicit-dynamics-1","topic-tag-drop-test","topic-tag-drop-test-simulation-1","topic-tag-error-explicit-dynamics","topic-tag-material-properties"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["270391","240"],"_bbp_author_ip":["96.7.74.173"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["2428"],"_edit_lock":["1670860828:200145"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["243798"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","270391"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["244166"],"_bbp_last_active_id":["244166"],"_bbp_last_active_time":["2022-12-16 00:19:14"]},"test":"tanmayo217gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/243798","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\/243798\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=243798"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
