I need to model cross-section of&nbsp; composite to&nbsp; ensure proper loading condition. As the normal direction ( material c- direction) of shell cannnot be changed I have to use transformation matrix to get material properties in the desired direction.The material properties can be seen in the figures. I am not sure if I am defining the model incorrectly or if my material properties is wrong but somehow, I am not getting expected results.&nbsp; And is there any simpler way to do it without using tranfromation matrix? I have tried all methods ( composite lay-up, defining stiffness matrix) but nothing seems to work. So any feedback would be highly appreciated.<\/p>\n<p>Thanks<\/p>\n<p>Manoz<\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/07\/07-07-2023-1688757678-Comp_Model.jpg\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/07\/07-07-2023-1688757691-0laminate.jpg\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/07\/07-07-2023-1688757847-mceclip0.png\"><\/p>\n","protected":false},"template":"","class_list":["post-292093","topic","type-topic","status-closed","hentry","topic-tag-acp-compositematerials-1","topic-tag-ls-dyna","topic-tag-material-properties"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["34611","3136"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["716"],"_edit_lock":["1689885181:188772"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["292093"],"_bbp_forum_id":["27814"],"_bbp_engagement":["3136","34611"],"_bbp_voice_count":["2"],"_bbp_reply_count":["9"],"_bbp_last_reply_id":["293680"],"_bbp_last_active_id":["293680"],"_bbp_last_active_time":["2023-07-18 17:32:43"]},"test":"mrijalaggies-ncat-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/292093","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\/292093\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=292093"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
