Abstract:
This paper presents the results of experimental studies of the crack propagation velocity and dynamic fracture toughness of St. 45 steel and D16T duralumin using a modified Kolsky method on a split Hopkinson bar. The results of microfractografic analysis of samples are given, and the fractal dimension is determined. The critical stress intensity factors are determine using the obtained fractal dimension values.
