,it appears that you want to pair the solid65 concrete model with a multilinear isotropic hardening (MISO) model. This does appear to be supported as long as you’re using the deprecated method to define the MISO model (as you’re doing in your command object). Note that the current method for defining a MISO model uses the PLAS label, as detailed in the TB command help page; for instance:
\nTB,PLAS,MATID,,,MISO
\nYou can see additional details and an APDL command example of defining the MISO model here: https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/corp\/v221\/en\/ans_mat\/amp8sq21dldm.html<\/a>. If you define the MISO model this way, then an error is thrown indicating that the PLAS option is not supported by solid65.
\nAnother option to combine a concrete model + a plasticity model, is to use current elements, e.g., solid185, which allows you to combine the Extended Drucker-Prager model with the MISO model; you can see supported material model combinations here: https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/corp\/v221\/en\/ans_mat\/elemmcpos050301.html<\/a>. Another option is to use the coupled damage-plasticity microplane model detailed here: https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/corp\/v221\/en\/ans_mat\/microplane.html<\/a>.<\/p>\n","protected":false},"template":"","class_list":["post-203230","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
