BOUNDARY-ELEMENT SOLUTION OF SOME STRUCTURAL-ACOUSTIC COUPLING PROBLEMS USING THE MULTIPLE RECIPROCITY METHOD.

In the paper we have developed a new formulation for solution of structural-acoustic coupling problems by boundary elements using the multiple reciprocity method. It is assumed that the structure is composed of plate components and is excited by the external or the internal noise source. The efficiency of the proposed formulation becomes especially remarkable if the boundary-value problem is to be solved repeatedly for different values of frequency. The accuracy of the numerical computations has been compared with the analytical solution in a test example. [ABSTRACT FROM AUTHOR]
