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)
