Abstract: A rotary traveling wave ultrasonic motor having a square prismatic shell stator is proposed. The stator contacts with the rotor through an interference fit, elastically deforms slightly, and then presses against the rotor. ...

Abstract: The inplane wave motion is analytically examined to address the stationary deflection, natural frequency splitting, and mode contamination of the rotationally ringshaped periodic structures (RRPS). The governing equation ...

Abstract: Tooth fracture is a major concern in the field of restorative dentistry. However, knowledge of the causes for tooth fracture has developed from contributions that are largely based within the field of mechanics. The present ...
