uniaxialMaterial('Hardening', matTag, E, sigmaY, H_iso, H_kin, eta=0.0)
This command is used to construct a uniaxial material object with combined linear kinematic and isotropic hardening. The model includes optional visco-plasticity using a Perzyna formulation.
matTag |
integer tag identifying material |
E |
tangent stiffness |
sigmaY |
yield stress or force |
H_iso |
isotropic hardening Modulus |
H_kin |
kinematic hardening Modulus |
eta |
visco-plastic coefficient (optional, default=0.0) |
