Abstract

In work, systematic studies of the dynamics of destruction processes and the evolution of defects are carried out on the example of artificial stone samples. During the experimental study of samples made of artificial stone after shock wave loading, destruction of the samples was not observed. At the same time, only the formation of radial cracks is observed. In contrast to ceramics, under the same load conditions, the rate of crack growth in artificial stone samples is, on average, 75 km/s. Software tools for 3D surface reconstruction, with high spatial resolution, were used to study the initiation and movement of cracks after shock-wave loading. 3D reconstruction of the surface makes it possible to observe and study the entire pattern of crack growth from the center to the periphery of the sample. The study and analysis of individual parts of the crack were carried out, particularly in the areas where their bifurcation and further growth occur. The nucleation and movement of local cracks in different places of the samples were also observed. The latter makes it possible to assert the existence of complex multi-level destruction of samples under the influence of shock-wave loading.
