4.14.5.1. Hardening MaterialΒΆ
- 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(int)integer tag identifying material
E(float)tangent stiffness
sigmaY(float)yield stress or force
H_iso(float)isotropic hardening Modulus
H_kin(float)kinematic hardening Modulus
eta(float)visco-plastic coefficient (optional, default=0.0)
