Abstract
The possibility of stable initiation and propagation of cracks from the edge of a notch with oblique front is established for specimens made of brittle tool materials. The compliance calibration of compact specimens weakened by notches with oblique front is obtained with the help of approximation of the experimental data by the method of least squares and applied to the evaluation of fracture toughness along the oblique profile in the process of wedging of a compact specimen.
