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)
