A dynamic model for the behavior of ultrasonically treatment materials is suggested. The microplastic strain piling up is related to the redistribution of the available defects and emergence of new ones on the microscale level as well as to the evolution of the available substructures and formation of new ones on the mesoscale level. The behavior of mild steel specimens subjected to ultrasonic shock wave treatment and to machining where the ultrasonic vibrations are applied directly by concentrator or magnetostrictive converter has been evaluated. The results obtained are reported.
