Thus, the property table is associated with the temperature data table.  On the other hand when MP command is used (e.g. MP,EX,MAT,c0,c1,c2,c3,c4) a fourth order polynomial as a function of temperature is defined: Property = C0 + C1(T) + C2(T)2 + C3(T)3 + C4(T)4<\/p>\n","protected":false},"template":"","class_list":["post-170557","topic","type-topic","status-publish","hentry","topic-tag-4422","topic-tag-materials","topic-tag-mechanical-apdl","topic-tag-special-purpose","topic-tag-structural-mechanics"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["2\/6\/2023 20:20"],"_bbp_forum_id":["27814"],"_bbp_author_ip":["209.182.204.162"],"_btv_view_count":["3879"],"siebel_km_number":["2014716"],"product_version":["18"],"km_published_date":["2011-01-11T21:12:00.000Z"],"family":["Structural Mechanics"],"application_name":["Mechanical APDL"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/170557","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/170557\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=170557"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
