Originální abstrakt
The paper concerns an experimental study on the crack deflection angle in a semi-circular disc made of an alkali-activated fine-grained composite under mixed-mode conditions. This study is supplemented by an extensive numerical analysis that calculates the crack deflection angles via generalized (multiparameter) fracture criteria. It is proved that the use of higher-order terms of the Williams expansion for the approximation of the crack-tip stress field leads to more accurate results. The influence of various parameters on the crack deflection angle is discussed, and recommendations on their proper choice are presented. The conclusions help in describing the crack behaviour under mixed-mode conditions more accurately.
