For a pressure of 0.005 psi, the maximum deflection is 0.1143 for my ANSYS results. However, when calculating analytically, the maximum deflection is 0.0625mm using this formula (w = pa^4\/64D where D = Et^3\/(12(1-v^2)) ). I used the same elastic constants. Can someone please help me. <\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/PQHBJW8R7ARN\/fixed-support-jpg.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/PQHBJW8R7ARN\/fixed-support-jpg.jpg\" alt=\"Fixed support.JPG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-53044","topic","type-topic","status-closed","hentry","topic-tag-structural-mechanics"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["25355"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["D\u0003?]"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["2724"],"_bbp_subscription":["257484"],"_bbpmt_movedon":["2022-08-26 08:22:26"],"_bbpmt_movedfrom":["27820"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["53044"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","183351"],"_bbp_voice_count":["2"],"_bbp_reply_count":["9"],"_bbp_last_reply_id":["145818"],"_bbp_last_active_id":["145818"],"_bbp_last_active_time":["2021-03-10 19:04:17"]},"test":"edasinor"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/53044","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\/53044\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=53044"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
