Abstract
When working material with the aid of shock-wave generating energy sources, the problem of tool fatigue occurs. This problem is reduced to a great extent by means of the inventive method, which prevents the occurrence of reflected tensile-force waves. This is achieved by permitting the pressure wave to pass into contact with porous material applied to the tool material, so that wave energy will be consumed by interference and heat generation in the porous material.
