| Ritz¿s method is applied to calculate accurate values of the lowest non-dimensional natural frequencies of a freely vibrating isotropic cube. The dependence of such frequencies and their quotients on Poisson¿s ratio is established. Vibration of a cube caused by a percussion is detected at a point by a laser interferometer. With the help of the tables and graphs provided and with the values of the first lowest frequencies obtained experimentally in a single test, Poisson¿s ratio and the shear modulus are calculated by means of elementary arithmetical operations. | |
