Structure-Acoustic Analysis; Methods, implementations and applications

Summary, in English

This thesis investigates structure-acoustic problems, which involve a flexible structure coupled to an enclosed acoustic fluid. In the literature, this type of problem is usually referred to as vibroacoustic problems or structure-acoustic



problems with fluid interaction. The thesis consists of two parts.



The first part provides an introduction into the field of



structure-acoustic analysis within the finite element framework.



The second part of the thesis comprises six papers in which analysis procedures and application examples for



structure-acoustic systems are developed.
