Analysis of propagation and interaction of shock waves in steel balls based on microstructure changes

Physical metallurgy and computer simulation methods were used to study the propagation and interaction of shock waves in steel balls subjected to conv ergent dodecahedrally symmetric shock waves. Conditions for the energy cumu lation and realization of the regular and the irregular type of interaction of shock waves were studied. Based on the results of microstructural inves tigations of intact samples, parameters of the shock-wave loading were calc ulated such as the pressure, the residual temperature, the time of isentrop ic flow of the substance under load, and the pressure profile behind the sh ock-wave front. A method for the restoration of the wave propagation patter n in the samples from residual microstructure changes is suggested.
