For example, when the yield stress ratio of your material in the x-direction is 1 (530\/530), the yield stress ratio in the y direction will be 0.96 (510\/530). If you don&#8217;t know your materials response in some directions, as an initial guess, you can set their behavior to that of an isotropic von Mises material (i.e. tensile stress ratios will be 1 and shear stress ratios will be 0.58). Please check the documentation to learn more about the Hill criterion: <a href=\"https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/corp\/v241\/en\/ans_mat\/amp8sq21dldm.html%23mataniso\">4.4. Rate-Independent Plasticity (ansys.com)<\/a>&lt;\/p&gt;&lt;p&gt;Anisotropic elasticity can also be considered in Ansys Mechanical but for large deformation application, like in metal forming, the anisotropic elasticity is typically neglected since the elastic deformation is a very small portion compared to plastic deformation. Check also more details in the documentation for anisotropic elasticity.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-365672","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/365672","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/365672\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=365672"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
