Die elastische Wellengleichung beschreibt das zeitliche Verhalten eines Kontinuums im Rahmen der klassischen linearen Elastizitätstheorie. In der vorliegenden Arbeit wird die Lösung des Cauchyproblems für dieses System linearer partieller Differentialgleichungen zweiter Ordnung mit Hilfe von Variationsmethoden präsentiert. Zunächst wird gezeigt, wie sich die elastische Wellengleichung aus der allgemeinen Bewegungsgleichung der Kontinuumsmechanik ergibt, wodurch das mathematische Modell motiviert wird. In weiterer Folge wird die variationelle Lösungsmethode diskutiert, welche auf dem Konzept von schwachen Lösungen beruht. Insbesondere wird die abstrakte Version dieser Methode in Hilberträumen erklärt. Die Beweise von Existenz, Eindeutigkeit ...
