I am trying to simulate the brittle fracture of concrete under three-point bending. The concrete beam is 40mm x 40mm x 160mm with span length of 120 mm. The beam is not reinforced with any other material and is supposed to have a brittle fracture after some loading (experimental value around 5Mpa).<\/p>\n
I would like to ask that how can I model the brittle fracture in static structural? I have defined the ultimate tensile and ultimate compressive load values in engineering data for the material. The simulation load is passing after the defined load values. I request if someone please guide me where I am doing wrong? I have used the PLC crack command to see the crack but I am not getting any thing there. I am only interested in getting the max load on which failure occurs and the crack on the material. The safety factor Mohr-Coulomb material model<\/a> is optional.<\/p>\n I made the model in both 3D<\/a> and 2D. Instead of drawing the physical rollers for the supports and loading, I have split the faces for the loading support at the top and bottom face for the two supports.For the 2D model it is quicker to solve but would be helpful if some expert may comment on whether the designed 2d model<\/a> is correct or not.<\/p>\n","protected":false},"template":"","class_list":["post-30799","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["2971"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["4097"],"_bbp_subscription":["235427"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["30799"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","897","154928"],"_bbp_voice_count":["3"],"_bbp_reply_count":["41"],"_bbp_last_reply_id":["69846"],"_bbp_last_active_id":["69846"],"_bbp_last_active_time":["2018-11-20 07:02:51"]},"test":"jackhero"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/30799","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\/30799\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=30799"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
