Hello all. I need help. <\/p>\n
How to simulate in lsdyna the crushing of a material (rock) due to compressive stresses or of an impact using the SPH or MLPG method.<\/p>\n
I tried to create a stone with SPH as a grid. As a material I set – elastic, or Coulomb-Mohr. And then I pressed with a rigid plate. But as a result the stone either does not receive any pressure at all, or the plate passes through the stone, or the stone is compressed but not crushed.<\/p>\n
Can someone tell me where to find a guide on using the partial method in lsdyna (MLPG, SPG, SPH). Or can someone tell me how to solve this problem.<\/p>\n","protected":false},"template":"","class_list":["post-379562","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["66399","13468"],"_bbp_author_ip":["104.28.192.94"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["275"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["379562"],"_bbp_forum_id":["27814"],"_bbp_engagement":["13468","66399"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["380128"],"_bbp_last_active_id":["380128"],"_bbp_last_active_time":["2024-08-24 07:02:31"]},"test":"mishchukyprotonmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/379562","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\/379562\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=379562"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
