Sažetak
During the service life many engineering components are subjected to complex cyclic loading and fatigue fracture. The purpose of this paper is to present the implementation of a robust cyclic plasticity theory for describing material behaviour near the crack tip in such loading case. The material used in experiment is the aluminium alloy AlCu5BiPb-T8. The experimental procedure included monotonic tensile tests, symmetric and unsymmetric strain-controlled fatigue tests, fracture toughness tests as well as fatigue crack propagation tests. Cylindrical specimens and single edge notch bend (SENB or three-point bend) specimens were used according to the standards ASTM EN 606 and ASTM E1820. Numerical material model is based on multi-component forms of isotropic and kinematic hardening variables in conjunction with von Mises yield criterion. The computational algorithm is implemented in the software ABAQUS and applied to the analysis of a crack growth near the notch. The accuracy of the computational procedure is tested by comparing the computed results with the real experimental data.
