This study offers three-dimensional vibration data for parallelepipeds having V-notches or sharp cracks. In the present work, a single-field Ritz procedure is employed, which includes a complete set of algebraic-trigonometric polynomials in conjunction with an admissible set of edge functions that explicitly model the three-dimensional stress singularities which exist along a terminus edge of the V-notch. Convergence studies demonstrate the necessity of adding the edge functions to achieve accurate frequencies. In this paper, accurate natural frequencies are presented for various terminus angles and two different aspect ratios.
