Originální abstrakt
The microtortuosity of the crack front induces a local mixed mode 1+2+3 even in case of the remote mode I loading. It causes a shielding effect not taken into account in standard procedures for evaluation of fracture characteristics. The main aim of this work is to perform a 3D BEM analysis of the elastic stress-strain field at the front of real-like intergranular cracks. Results of this analysis are evaluated in terms of the integral effective stress intensity factor keff related to the intergranular crack front. Quantitative estimation of the corresponding shielding level can be used for correcting values of fracture toughness in order to get intrinsic component characterising well the real resistance of grain boundaries against the unstable crack growth initiation.
