Hardening

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.

uniaxialMaterial Hardening $matTag $E $sigmaY $H_iso

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)
