✦ Synopsis

The distribution of the natural frequencies has a recognized importance in the Statistical Energy Analysis of vibrations of continuous structures. A method is introduced for approximating to the distribution of the natural frequencies for structures characterized by matrices of stiffness and mass coefficients, without resolving specific frequencies. Simple examples are given. Potential uses include frequency analysis for incompletely defined or sampled structural matrices.
