I am trying to run a fatigue analysis using fatigue tool on a dogbone sample subjected to axial tensile and compressive loads, whilst also subjected to a horizontal clamping preload via a contact pad. The contact pad imparts a contact stress which I want to include in the fatigue analysis.<\/p>\n<p>The clamping force is applied as a first time step, prior to appling a compressive axial load in time step 2, which is then reversed in time step 3. The clamping force remains throughout.&nbsp;<\/p>\n<p>I am trying to run the analysis without reversing the clamping load and only cycling the compressive and tensile loading. I have tried using solution combinations however, this still reverses the clamping load.&nbsp; The clamping load also seems to be applied at the same time as the axial loading instead of following the application via the time steps. ie clamping load -&gt; axial compressive loading -&gt; axial tensile loading.<\/p>\n<p>Any help would be greatly appreciated.<\/p>\n<p>Kind regards,<\/p>\n<p>Morgan<\/p>\n","protected":false},"template":"","class_list":["post-357655","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["296127","490"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["879"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["357655"],"_bbp_forum_id":["27791"],"_bbp_engagement":["490","296127"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["357970"],"_bbp_last_active_id":["357970"],"_bbp_last_active_time":["2024-03-19 16:44:08"]},"test":"morgan-ramanauskas-2021uni-strath-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/357655","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\/357655\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=357655"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
