I want to know the tangent modulus value for PLA that can be used in Ansys. Is there anyone who can help me in this regard? As the stress-strain curve of PLA is downward in plastic region, even if I take a slope value from any point in plastic region, its negative and I can not use negative values for tangent modulus in Ansys. I am really stuck with this problem and can not proceed further. Any kind of advice is welcome. I really need it. I dont know how to get the tangent modulus value for PLA.nThank younKind RegardsnAqibn<\/p>\n","protected":false},"template":"","class_list":["post-47110","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["19307"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["?\u001f?S"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1781"],"_bbp_subscription":["253907"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["47110"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","179796"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["123862"],"_bbp_last_active_id":["123862"],"_bbp_last_active_time":["2020-08-09 19:49:54"]},"test":"aqibdrmc"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/47110","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\/47110\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=47110"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
