When I preload the bolt in step 1 at 5000N &amp; lock in subsequent steps. The working load at end of simulation comes out to be more than 5000 N ( somewhere around 5003 N). Isn&#039;t it wrong?&nbsp;I also tried simulating a simple double shear joint with 10 N load &amp; 5000 N pretension. The result comes same as 5003N working load at bolt.&nbsp;Also FOS is 0.1 at just 10N load which should not be the case in reality. Can you please help where the problem could be.<\/p>\n","protected":false},"template":"","class_list":["post-161597","topic","type-topic","status-closed","hentry","topic-tag-peteroznewman"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_view_count":["236"],"_bbp_likes_count":["0","0"],"_bbp_forum_subforum_count":["0"],"_btv_view_count":["3373"],"_bbp_subscription":["239781"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["161597"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","221921"],"_bbp_voice_count":["2"],"_bbp_reply_count":["12"],"_bbp_last_reply_id":["189956"],"_bbp_last_active_id":["189956"],"_bbp_last_active_time":["2021-08-27 23:45:59"]},"test":"ashish-choudharyfupro-in"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/161597","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\/161597\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=161597"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
