Lomová houževnatost z tříbodového ohybu vzorků z kvazikřehkých materiálů: korekce vzhledem k šířce zářezu
Original language description
The paper introduce the ifluence of the starting notch width on a crack growth in three-point bending specimens that are most frequently used specimens for fracture laboratory testing, especially of quasi-brittle cement-based composites. There are analyses of three geometrically different configurations of the specimens. It is shown that the values of fracture toughness obtained from the tests of specimens with larger widths of the starting notch can be overestimated. Correction functions for selected testing configurations are presented.
