Abstract : The response of oval rings of varying eccentricity for several types of applied loading conditions have been obtained. It is found that the magnitude as well as the frequency of oscillation of the deflection is dependent upon the ring eccentricity. In addition, the dependence of the deflection upon circumferential position is shown to be related to the local radius of curvature. Other results include the determination of the resonance frequencies of the ring as well as the existence of a double resonance 'peak' observed via the classic 'beat' phenomenon.
