Abstract

This investigation is devoted to the problems concerning the reliability of units subjected to an erosion attack of heterogeneous liquid mediums containing gas vapor and denser fine-dispersed substances. The results of the simulation of an ambient dynamic action on solid barrier surfaces, and the response of the materials with heterogeneous structures and protecting covers to repeated external pulse attacks with different intensities are presented. The structural-energetic model of the materials’ cavitation and erosion wear is given. The physical-mechanical criteria and time wearing parameters are also presented.
