It consists of 400 alternating layers of 0.25 mm thick steel and 0.003 mm thick epoxy along the height of the cylinder. All layers are bonded together with bonded contact.&lt;\/p&gt;&lt;p&gt;Besides using the volume averaging method to homogenize the composite material, is there a specific setting for simulating periodic structures, such that drawing only one layer of steel and epoxy is sufficient for analysis?&lt;\/p&gt;&lt;p&gt;Thank you\uff01&lt;\/p&gt;&lt;p&gt;Wei-Hao Chang&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-398588","topic","type-topic","status-answered","hentry","topic-tag-compositematerials-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27791"],"_bbp_topic_id":["398588"],"_bbp_subscription":["42303","23687"],"_bbp_author_ip":["118.163.160.178"],"_bbp_last_reply_id":["403644"],"_bbp_last_active_id":["403644"],"_bbp_last_active_time":["2025-01-06 00:05:41"],"_bbp_reply_count":["3"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["42303","23687"],"_btv_view_count":["216"],"_bbp_topic_status":["answered"]},"test":"weihaochang"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/398588","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/398588\/revisions"}],"predecessor-version":[{"id":403645,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/398588\/revisions\/403645"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=398588"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
