Kinematic Hardening
RecurDyn supports only the bilinear kinematic hardening, and therefore, it is defined by only 1 parameter:
•Kinematic Hardening (
): the kinematic hardening
modulus
The linear kinematic hardening is defined by the differential equation:

Where,


Note that the Kinematic Hardening (
) input field will only be visible
in the plastic material dialog box if Plastic / Isotropic + Kinematic was
selected in the Material dialog box.

Figure 2 Isotropic+Kinematic Hardening input
If Plastic / Isotropic was selected for the material
type, then the Kinematic Hardening (
) input field will not be
visible.
