✦ Synopsis
In previous papers, the basic mechanisms of the ballistic effect, e.g. the fact that samples are ejected with high velocity, associated with the fracture of brittle materials during ultrasonic fatigue loading, were studied. In this technical note, the point of main effort is to extend the results such that for practical purposes the ejection velocities (and thus the damage potential) can be quickly estimated, e.g. without employing the computer intensive calculation procedure. The validity of the method is checked by e.vperiments performed on soda lime glass rods. Special emphasis is given to test procedures, which are commonly used in ultrasonic fatigue.
