This bachelor’s thesis depicts the source localization of acoustic source in solid bodies. For this purpose two fundamental equations are introduced, the equation of motion and the wave equation. Both equations were discretized in space with the Finite Element Method and in time with the Newmark’s scheme. Beside the simulation of a wave that spreads out in space, it is possible to simulate the wave in time-reverse such that the wave propagates back to its origin. The equations were solved numerically within MATLAB. Therefore an existing finite element implementation, which was provided by the chair of Computation in Engineering of the Technische Universität München, was extended.     «
