steels, it needs to be noted that the yield strength only characterizes the elastic response of the metal. For concretes, the unconfined compressive strength parameter not only describes the elastic response, but the inelastic (plastic) response including the shear failure envelope, compressibility (...
In addition to the tabulated plasticity inputs, the Tabulated Johnson-Cook model also includes a failure criteria as a function of triaxiality, Lode parameter, temperature, strain rate, and element size. While this mater...

Elasto-plasticity with linear isotropic hardening can be compared to MAT24. Just be aware that "ETAN" is not the linear hardening modulus "K", but the resulting stiffness ETAN=(E*K)/(E+K) with Young's modulus "E". 2D: plane strain and axial symmetry ...
For example, if you change the model type of a custom material from a Linear Elastic Isotropic to Plasticity - von Mises, when you create a new Nonlinear Simulation study, the model type for the custom material would be Plasticity - von Mises. You can view the location of the custom mater...
Since both G and the elastic modulus E are required to be positive, the quantity in the denominator of G must also be positive. This requirement places a lower bound restriction on the range for Poisson's ratio, n > -1 Bulk Modulus from Hydrostatic Pressure When an isotropic material spec...
