The compressive stress distribution was established by subjecting the column to a 1.0 lbf compressive load at the free end and the results transferred into the buckling analysis. The <em>load multiplier<\/em> output value I obtained was 1196.8 and 4776.7 for Mode 1 and Mode 2 respectively. I did a hand-calculation using the Euler Column Formula for the particular end conditions and obtained a critical load of 4766.787 lbf which closely matches the value for Mode 2. So what is the significance of the mode 1 value? Why does ANSYS return this value? If such a column is ever designed, what load would it buckle at, in the real world ? I am just trying to wrap my head around this correlation.<\/p>\n<p><\/p>\n<p>Thanks!<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/df75fc70-0a0c-4790-aba8-a94c013bf763\/e8a8227d-d339-4329-bcff-a95b0144981e_mode-1.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/df75fc70-0a0c-4790-aba8-a94c013bf763\/61997085-7246-41ae-9f0c-a95b0144a36f_mode-2.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-30421","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["2591"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["753"],"_bbp_subscription":["236976"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["30421"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","65357"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["64206"],"_bbp_last_active_id":["64206"],"_bbp_last_active_time":["2018-09-15 13:25:34"]},"test":"sujaysanjiv"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/30421","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\/30421\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=30421"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
