Sažetak
An efficient computational strategy for modeling combined isotropic and kinematic hardening responses in large strain elastoplastic analysis has been presented. Small elastic strains are assumed which is justified for ductile metals. The integration algorithm employs closest point projection strategy which is analogous to the algorithm of small strains. A consistent elastoplastic tangent modulus ensures high convergence rates in the global iteration approach. The integration algorithm is implemented in the formulation of 7-parameter shell finite element allowing direct implementation of three-dimensional constitutive models. The numerical example illustrates robustness and efficiency of the proposed algorithm.
