Time-Domain Implementation, repeating the essential equations from previous chapters. In the last part, several examples are given ranging from simple two-dimensional geometries to three-dimensional arch dam models. The results are compared to analytical results and to results from the literature to confirm the accuracy and efficiency of the procedure.

Fortunately, with the finite element method, engineers have a

Model Problems,ple as possible but general enough to allow a conclusive discussion. In the following chapters they will be used to investigate some commonly used numerical solutions and some new methods which are the main contribution of this work. A similar collection of example problems for wave propagation can be found in [Gra75].

The internal structure is usually of minor interest and has generally no physical significance but general attributes such as stability, and minimal realization have to be investigated.

Durch Wärmeleitung, Wärme aus radioaktiven Zerfällen und durch heiße magmatische Gebiete wird in der Erdkruste ein Temperaturgradient erzeugt, der an der Erdoberfläche 3 °C pro 100 m ausmacht (die normale geothermische Tiefenstufe wird m
