4.14.1.9. Steel01ThermalΒΆ

uniaxialMaterial('Steel01Thermal', matTag, Fy, E0, b, a1, a2, a3, a4)

This command is the thermal version for 'Steel01'.

matTag (int) integer tag identifying material
Fy (float) yield strength
E0 (float) initial elastic tangent
b (float) strain-hardening ratio (ratio between post-yield tangent and initial elastic tangent)
a1 (float) isotropic hardening parameter, increase of compression yield envelope as proportion of yield strength after a plastic strain of \(a_2*(F_y/E_0)\) (optional)
a2 (float) isotropic hardening parameter (see explanation under a1). (optional).
a3 (float) isotropic hardening parameter, increase of tension yield envelope as proportion of yield strength after a plastic strain of \(a_4*(F_y/E_0)\). (optional)
a4 (float) isotropic hardening parameter (see explanation under a3). (optional)
