Detailed Description
Uniaxial material model for steel.
provides the abstraction of a bilinear steel model with isotropic hardening. The model contains a yield strength of fy, an initial elastic tangent of E0, and a hardening ratio of b. The optional parameters a1, a2, a3, and a4 control the amount of isotropic hardening (default values are provided). Specification of minimum and maximum failure strains through the -min and -max switches is optional and must appear after the specification of the hardening parameters, if present. The argument matTag is used to uniquely identify the material object among material objects in the BasicBuilder object.
