It is located on a thick plate, and a vertical force of 4000N is being applied on a line on the top of the cylinder. According to Hertzian contact theory, a contact pressure of 682 MPa will be created.&nbsp;<\/p>\n<p><\/p>\n<p>I would like to ask, if I delete this cylinder from my 3D model, and instead, I use vertical load on the plate directly or using nodal force on the plate directly, how can I make my simulation result closer to the real situation where I apply the force on the deformable cylinder. My results are too different.&nbsp;<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>I know that applying force on the cylinder will create a very narrow surface to surface contact and it is not equal to nodal or line force anymore. The thing I am looking for is an equivalent force which mimics the behavior of cylinder (surface to surface contact)<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Is there any method to solve this problem?<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Thank you.<\/p>\n","protected":false},"template":"","class_list":["post-37025","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["9200"],"_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"],"_btv_view_count":["709"],"_bbp_subscription":["239304"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["37025"],"_bbp_forum_id":["27791"],"_bbp_engagement":["160648","163285"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["91639"],"_bbp_last_active_id":["91639"],"_bbp_last_active_time":["2019-08-08 15:16:26"]},"test":"alisafian"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/37025","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\/37025\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=37025"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
