In this paper, the basic hypotheses of vibrations of the parallelepiped with two free opposite surfaces and the two other subjected to the Sommerfeld boundary conditions are given. They serve for a derivation of the governing equations which are analysed in some detail. The numerical algorithms are proposed and the calculation results are given allowing to estimate the validity of two-dimensional theories.
