In the present article a comparative analysis is made between the linear and the nonlinear kinematic hardening assumption for elastoplastic materials. A solution procedure which preserves a quadratic rate of convergence is used for the simulation of a typically adopted nonlinear kinematic hardening law. Numerical computations and results are reported. A comparison is made between the adoption of the assumption of linear versus nonlinear kinematic hardening rule by considering different types of material properties. The analysis allows to have a better insight on the conditions upon which such assumption may be considered as effective.

Abstract

In the present article a comparative analysis is made between the linear and the nonlinear kinematic hardening assumption for elastoplastic materials. A solution procedure which preserves a quadratic rate of convergence is used for the simulation of a typically adopted nonlinear kinematic hardening law. Numerical computations and results are reported. A comparison is made between the adoption of the assumption of linear versus nonlinear kinematic hardening rule by considering different types of material properties. The analysis allows to have a better insight on the conditions upon which such assumption may be considered as effective.
