Summary

The propagation of elastic and plastic waves in arbitrary spatial trusses under impact loading is considered in this paper. Particular attention is payed to the derivation of the equations which are needed to determine the distribution of the waves at the pins. Subsequently, the equations are written compactly as a matrix equation which is solved numerically. Various examples illustrate the method.

Übersicht

In dieser Arbeit wird die Ausbreitung von elastischen und plastischen Wellen in beliebigen räumlichen Stabwerken unter Stoßbelastung behandelt. Dabei wird der Herleitung der Gleichungen, die zur Ermittlung der Wellenaufteilung an einem Knoten benötigt werden, besondere Aufmerksamkeit gewidmet. Die Gleichungen werden anschließend zu einem Matrizensystem zusammengefaßt, das numerisch gelöst wird. Beispiele illustrieren die Methode.
