Ritz's method is applied to calculate the dimensionless natural frequencies of a cube of homogenous, isotropic, elastically linear material. This method is optimized in this three-dimensional problem with object to get the most suitable exponents of the power series proposed as solution for the displacements. The results obtained for the frequencies of a free vibrating cube are analysed in order to determine their dependency upon the Poisson's ratio. Results from that numerical calculation are compared with approximate elementary solutions. A percussion applied to a cube excites its vibration and the detection of this vibration by means of a speckle interferometry in one of its points permits to obtain experimentally the natural frequencies of vibration. The obtained numerical and experimental results are compared and the agreement is good. | |
