WebThe command is not for use with kinematic hardening material properties (such as TB,BKIN) or the shape memory alloy material model (TB,SMA). INISTATEwith elastic strain alone is not supported for gasket materials (TB,GASK) and hyperelastic materials (TB,HYPER, TB,BB, TB,AHYPER, TB,CDM, TB,EXPE). INISTATEwith initial stress … WebA generic kinematic hardening rule that is associated with and can be expressed as follows: (7.62) where = the translational direction of a yield surface dλ 5 = the scalar that can be determined from the consistence condition There are three kinematic hardening rules that fall into this category and can be expressed as Prager's rule (1955): (7.63)

Web1 jan. 2024 · However, for kinematic hardening, the plastic strain reverses direction with stress and takes on negative values. It has been observed that when the stress applied is compression at first, the plastic strain takes on a negative value and remains constant from that point on for an isotropic material.
