Abstract:
This work presents the analysis of the forced vibrational response of an elastic rectangular parallelepiped. Normal mode solutions were obtained for the following boundary conditions: 1. Six rigid-lubricated faces, 2. Four rigid-lubricated and two stress-free faces. In the forced vibration analysis solutions were obtained for an impulsive and a step point load. For the both cases of boundary conditions, computer programs were developed in order to calculate the displacements of a sample block. In the numerical calculations point of application of the force and the point at which, displacements are sensed were taken in the rectangular block.
