Based on the strain superposition principle, the phenomenon of mean stress reduction in metals plastic processes with vibration is explicated. and the mechanism of volume effect is described.
A new calculation method, base the method of equivalent additional plastic loads on modes ofvibrationsuperposition method is studied.
