The datasheet of the producer of this material gives me the curves attached, that represent the thermal strain (deltaL \/ L_0) vs temperature, for the case alpha_P (parallel coefficient of thermal expansion) and alpha_N (normal coefficient of thermal expansion).<\/p>\n<p>I have two doubts about the graph:<\/p>\n<p>1) How can I obtain the curve to be inserted in ANSYS for what concerns the coefficient of thermal expansion (alpha vs T)? Each coordinate of the plot represents a thermal strain, so in which way I can pass from thermal strain to alpha?<\/p>\n<p>2) In the datasheet, which is the difference between the parallel coefficient of thermal expansion and the normal one?<\/p>\n<p>Thanks,<\/p>\n<p>Jacopo<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/10-02-2024-1707559717-Cattura.JPG\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-350287","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["302591","240"],"_bbp_author_ip":["23.52.43.10"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["2198"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["350287"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","302591"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["350965"],"_bbp_last_active_id":["350965"],"_bbp_last_active_time":["2024-02-13 07:34:40"]},"test":"jacopo-bardianipolimi-it"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/350287","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\/350287\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=350287"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
