I am currently using the Johnson-Cook model to simulate the response of a SS304 structure which suffers an impact at 10m\/s. Due to the relatively&nbsp;high strain rates, the material would heat up affecting the material properties locally, and the J-C equation should take into account the temperature. My question is, is Explicit Dynamics calculating the energy dissipation using the material density, specific heat and integrating flow stress over plastic strain to compute the temperature increment locally at each node and including this thermal softening within the simulation? Or is it neglecting the temperature increase?<\/p>\n<p><\/p>\n<\/p>\n<p>Thank you for your help,<\/p>\n<p>Victor Bautista&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-160530","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_view_count":["236"],"_bbp_likes_count":["0","0"],"_bbp_forum_subforum_count":["0"],"_btv_view_count":["284"],"_bbp_subscription":["231788"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["160530"],"_bbp_forum_id":["27814"],"_bbp_engagement":["13386","213117","234433"],"_bbp_voice_count":["3"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["186095"],"_bbp_last_active_id":["186095"],"_bbp_last_active_time":["2021-10-15 17:57:04"]},"test":"vbautista2016my-fit-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/160530","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\/160530\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=160530"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
