   Abstract:
   The equations governing free, in-plane vibrations of variable curvature arches are derived and solved numerically to obtain frequencies and mode shapes for parabolic, sinusoidal and elliptic geometries. Included are experimental validations of the lowest four predicted frequencies and mode shapes for parabolic arches.
