| A solution of the first boundary problem for forced vibrations of an elastic prism is obtained. By a superposition method, this problem is reduced to a quasi-regular infinite linear system. The prism eigenfrequencies were calculated on the basis of the sufficient condition of existence of bounded solution for a quasi-regular infinite system, Application range of the approximate method at simple boundary conditions has been studied. |
