Sažetak
Efficient numerical algorithms for modeling of elastoplastic responses of shell structures are proposed. Both small strain and large strain formulations are presented. The small strain formulation employs a realistic highly nonlinear and temperature dependent hardening model, while an isothermal free energy-based formulation incorporating isotropic and kinematic hardening is applied for the large strain analysis. An associative flow rule and von Mises yield criterion are employed. In order to ensure a high convergence rate in the global iteration approach, algorithmic tangent moduli are derived for both formulations. Numerical example demonstrates robustness and efficiency of the proposed algorithms.
