After releasing and forwarding the sheet another punch action is performed until a constant radius across the work piece is achieved. The contacts are defined as frictional (nonlinear), which are partly applied and released in each bending cycle.<\/p>\n<p>When researching on LS-DYNA I found out that it is also useful for contact problem calculations and one of the core-competency is &quot;highly nonlinear transient dynamic finite element analysis&nbsp;(FEA) using explicit time integration&quot;.<\/p>\n<p><\/p>\n<\/p>\n<p>When using LS-DYNA instead of static structural analysis with Mechanical APDL:<\/p>\n<p>Question #1: What are the differences regarding the calculation time (what solver is faster) ?<\/p>\n<p>Question #2: Are there some other advantages of LS-DYNA?<\/p>\n","protected":false},"template":"","class_list":["post-164654","topic","type-topic","status-closed","hentry","topic-tag-ansys-mechanical","topic-tag-contact","topic-tag-ls-dyna","topic-tag-mechanical-apdl","topic-tag-static-structural"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["2365"],"_bbp_likes_count":["0"],"_bbp_subscription":["241871"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["164654"],"_bbp_forum_id":["27814"],"_bbp_engagement":["193","13468","185792","241871"],"_bbp_voice_count":["4"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["199780"],"_bbp_last_active_id":["199780"],"_bbp_last_active_time":["2021-12-22 05:48:50"]},"test":"theodor-middeldorfalumni-fh-aachen-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/164654","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\/164654\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=164654"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
