Wave Dispersion Mechanisms in Large Space Structures.

Abstract

This report describes an investigation into wave dispersion phenomena in large lattice space structures. Particular results were 1) That local member dynamic characteristics significantly influence global dynamic response; 2) That it is possible to increase dispersion of wave energy in lattice-truss structures by adopting a nonuniform lattice construction; and 3) That local member dynamics characteristics require detailed modeling techniques which are capable of capturing member bending behavior in order to assess, realistically, the influence of local phenomena on global dynamic response.
