To clarify the mechanism of an ultrasonically forced insertion (USFI), frictional stresses and displacements on the contact surface of a metal rod and a metal plate in the USFI process were analyzed by finite element method. Frictional stresses under two conditions were compared. One of the conditions was a horn and the metal rod moving with static displacement. The other was the horn and the metal rod moving with vibrational displacement. The amplitude and distribution of frictional stresses under the vibrational condition were small and almost flat, respectively. Axial and radial displacements of the plate and rod on the contact surface in a USFI process were also analyzed. As results, it was clarified that the USFI had the effect of reduction of frictional stress.
