But since that is a legacy element, I have seen the CPT215 being recommended. I have seen that you can use the Druker-Pager Model with it. I have the following properties for concrete: nUltimate Tensile Strength = 2.3MPa nUltimate Compressive Strength = 40MPanBiaxial compressive strength = 48MPa nUltimate compressive strength for a state of biaxiam compression superimposed on hydrostatic stress state = 58MPa nUltimate compressive strength for a state of uniaxial compression superimposed on hydrostatic stress state = 69MPa nnI was wondering how I can input these values to model the concrete? I have very limited knowledge of inputting commands into ANSYS. Could someone please show me a similar example\/instructions to how I can do this? nI have tried to use the Mechanical APDL to write the script for SOLID65, but since I am modelling pull-out of rebar (with ribs) from concrete, it wasn&#8217;t letting me to input some values as it was saying some of the angles are over the error limit. nAlso, there is a NL Concrete material in the ANSYS Engineering Data Library, if I were to use that, would that still allow me to see the cracks in concrete? nIf someone could help it would be wonderful! Thank you! n<\/p>\n","protected":false},"template":"","class_list":["post-49394","topic","type-topic","status-closed","hentry","topic-tag-concrete","topic-tag-concrete-non-linear"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["21628"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["?^3\u0017"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1300"],"_bbp_subscription":["254782"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["49394"],"_bbp_forum_id":["27791"],"_bbp_engagement":["50680","166307","180667"],"_bbp_voice_count":["3"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["137737"],"_bbp_last_active_id":["137737"],"_bbp_last_active_time":["2021-01-05 20:32:54"]},"test":"to2020"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/49394","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\/49394\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=49394"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
