I used Shell281 to model a Graphite-Epoxy composite plate under SSSS boundary condition and the result I got is close to my validation results. However, when I used Solid185 to model the same plate, the results obtained are no longer agreed with the one obtained using Shell281. I have set the layer construction to layered solid and I have defined the fibre orientation using the shell sections. So I am wondering is it the problem is due to my setting? <\/p>\n<p>When using Shell281, the SSSS B.C. were set by setting the 4 edges to have zero displacements in z-direction (upward direction) and the rotation normal to the edge was also set to zero (i.e. ROTX = 0 when x=0 and x=a &amp; ROTY = 0 when y=0 and y=b). <\/p>\n<p>While for Solid185, I set all edges to have zero displacements in the y-direction (upward direction) and zero displacements for the DOF parallel to the edge (i.e UX=0 when z=0 and z=b &amp; UZ=0 when x=0 and x=a). i had modelled it as a solid and divided the thickness into the required number of layers when meshing.<\/p>\n","protected":false},"template":"","class_list":["post-165327","topic","type-topic","status-closed","hentry","topic-tag-ansys-apdl","topic-tag-element-types-2","topic-tag-modal-analysis"],"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":["1503"],"_bbp_likes_count":["0"],"_bbp_subscription":["245041"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["165327"],"_bbp_forum_id":["27791"],"_bbp_engagement":["58821","245041"],"_bbp_voice_count":["2"],"_bbp_reply_count":["11"],"_bbp_last_reply_id":["202064"],"_bbp_last_active_id":["202064"],"_bbp_last_active_time":["2022-01-10 06:54:09"]},"test":"hozc-wg17student-tarc-edu-my"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/165327","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\/165327\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=165327"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
