The <span style=\"display: inline !important; float: none; background-color: transparent; color: #3b3b3b; font-family: Arial,Helvetica,sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;\">force is alternating between 0 and a constant maximum force<\/span> and it is applied slowly. So in every cycle the cross section of the part should be decreasing, the stress should be increasing and the plastic strain should be increasing.<\/p>\n<p><\/p>\n<p>My first idea was to simulate this as a static structural simulation using isotropic hardening. The problem is that the total displacement and plastic strain is not increasing due to the cyclic loading. When using a transient structural simulation the total displacement and plastic strain is increasing a little bit in every cycle. What is the difference? Is the decreasing of the cross section considered by the static and transient analysis? The part is quite complicated, so I prefer the static structural analysis. What is the best way to do this?<\/p>\n<p><\/p>\n<p>I use Workbench 19.<\/p>\n<p><\/p>\n<p>Thanks for your help<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-30913","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["3085"],"_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":["2925"],"_bbp_subscription":["236846"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["30913"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","897","158256"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["66656"],"_bbp_last_active_id":["66656"],"_bbp_last_active_time":["2018-10-16 11:27:37"]},"test":"maddes"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/30913","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\/30913\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=30913"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
