Notch effects under ultrasonically vibrating stress.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1988 In this study, stress concentration factors and fatigue strength reduction factors are obtained in the case of a round bar of mild steel with a V-groove under ultrasonically vibrating stress. The stress concentration factors are determined by analysis on eigenmodes using FEM.

A generalised approach to torsionality maximisation in longitudinal-torsional ultrasonic devices [PDF]
, 2011 A longitudinal-torsional vibration mode has many applications in ultrasonic systems. Obtaining this behaviour could be achieved either by coupling the longitudinal and torsional modes or by degenerating the longitudinal mode, but the results may be ...
