Abstract
Use new way for analysis of the fracture of the destruction material derived from the fractal view on the fracture surface give possible to receive information in the case when traditional analysis don-t give result. It is the very perspective direction provides use the low of the amplitude normalized of the Hurst, which define the level on the self-similarity for the self-affine object. The development new methodic allow calculation of the statistic distribution of the local fractal dimension (Hurst exponent) of the fracture surface and to find dependence between crack growth of the crack and the maximum size of the area, where calculation the index of the Herst. By this methodic it has been possible to define of the crack growth rate in the material steel Х18Н10Т has destruction by the vibration mechanism.
