Mechanism of reducing effective dry friction under shock and vibration effects (to theory of technogenic seismic sources)

Abstract

A simple mechanical model illustrates that even very weak vibration or shock impacts can cause a significant displacement of bodies in contact by dry friction. The model is studied using the concepts of effective friction coefficients under vibration and elements of the vibrational displacement theory. The results are compared with those of earlier and new experiments. Their application to the theory of man-made earthquakes and the problem of increasing oil recovery from petroliferous layers through vibration effects is discussed.
