I have two stress-strain curves for tension and torsion and want to implement them to define the behavior under biaxial static loading, but i am confused on how to assign them to one material model. My first try was to use TB,EXPE but in the manual it says that an additional model is needed and I am unsure on how to combine them. I am relatively new to APDL and thankful for any advice!&nbsp;&lt;\/p&gt;&lt;p&gt;Thanks.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-382063","topic","type-topic","status-publish","hentry","topic-tag-add-material","topic-tag-curve-fitting"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["453477","79"],"_bbp_author_ip":["130.75.237.209"],"_btv_view_count":["255"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["382063"],"_bbp_forum_id":["27791"],"_bbp_engagement":["79","453477"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["383015"],"_bbp_last_active_id":["383015"],"_bbp_last_active_time":["2024-09-18 14:05:22"]},"test":"lketelsen96gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/382063","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\/382063\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=382063"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
