Original Abstract

The paper is devoted to an analysis of the crack deflection angle in a semi-circular disc made of a fine-grained composite based on water glass-activated slag. Three-point bending together with an inclined crack ensures the crack propagation in I+II mixed mode. Generally, concrete material exhibits quasi-brittle fractme behavior. which is difficult to understand. Multi-parameter fracture mechanics concept shall help to describe the crack propagation and influence of choice of a suitable distance for application of generalized fiacture criteria is investigated. In the work, the well-known Maximum Tangential Stress (MTS) criterion as well as Strain Energy Density (SED) criterion are applied in their multi-parameter form find the initial kink angle. Williams power expansion is used to approximate the crack-tip stress field. Its coefficients need to be calculated numerically via combination of the finite element solution and over-deterministic method. Results are discussed and recommendations are stated regarding the critical length parameter as well as the number of the Williams expansion coefficients.
