Combining Kinematic and Isotropic Hardening Material Plasticity Models together
You can define combined hardening metal plasticity (Kinematic and Isotropic) in Engineering Data and/or MAPDL, but you have to use the Chaboche nonlinear kinematic model for the kinematic part.
You cannot just combine BKIN with BISO directly.
Note: for the Chaboche nonlinear kinematic, if n=1 and gamma =0, it reduces to a bilinear representation.
Refer to Table 7.1 of MAPDL Material Reference Manual for a list of all allowable nonlinear material combinations.
