I used the 60% rule to have the vaue of the maximal tangential stress from the maximal normal stress. Then also since i do know the value of the maximal tangential energy i have just multiplied the value of the maximal normal energy by 60%.<\/p>\n<p>I am having difficulties in convergence. My question is can i use the CZM mixed mode eventhough i know that the tangential stresses are dominant (but there are normal ones that i can not ignore)? If i used the CZM mode II i will ignore the normal stresses and this is not the case. Another question, can i put both modes of fracture but with determening which is the dominant one? Is the 60% of normal stress is always the tangential stress? Can the problem be the value of the tangential energy that i have assumed to be 60% of the normal energy?<\/p>\n<p>Thanks in advance.<\/p>\n<p><\/p>\n<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/1C43HLF1QDDY\/czm-debonding.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/1C43HLF1QDDY\/czm-debonding.png\" alt=\"CZM debonding.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-53758","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["26081"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["?y?3"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["616"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["53758"],"_bbp_forum_id":["27791"],"_bbp_engagement":["10","1759"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["150179"],"_bbp_last_active_id":["150179"],"_bbp_last_active_time":["2021-04-21 06:10:05"]},"test":"mustafa_shqair"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/53758","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\/53758\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=53758"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
