On the Similarity of Dynamic Destructive Processes in Metals of Different Geometry under the Effect of External Impacts with Various Amplitude-Time Characteristics

Abstract

In this paper, we aimed to establish the similarity of dispersion of various metals at high-intensity loading. Characteristics of the dispersing products and the cascade of arising dissipative structures (the inner surface roughness of the destruction centers, the cascade of the slip bands of the crystal lattice, the cascade of destruction centers, and the roughness of the destruction surface) were quantified on the basis of fractal geometry using the interactive image analysis system (IIAS) package. We numerically simulated destruction in loaded samples using the TIM 3D Lagrangian technique.
