What is Formulation of Implicit Stress Integration and Consistent Tangent Modulus for an Anisotropic Hardening Constitutive Model about?
An anisotropic hardening constitutive model based on the generalized isotropic hardening (GIH) rule was implemented into the nonlinear ®nite element method. The GIH rule describes discrete formation of homology centers and simultaneous hardening of both inner and outer yield surfaces. Consequently, yielding in the ®eld of reverse loading can be accurately modeled by this rule. In order to preserve the accuracy of nonlinear ®nite element analysis, an implicit stress integration technique employing the generalized trapezoidal rule was applied to the GIH constitutive equation. Furthermore, the consistent tangent modulus was formulated and coded into a nonlinear FEA program, which has the advantage of the quadratic rate of convergence in Newton's iteration. Accuracy and convergence were successfully veri®ed through examples, and thus the anisotropic hardening constitutive model could assess the plastic straining mobilized in overconsolidated state and versatile loading sequences.
