✦ Synopsis

Abstract

Metal hollow sphere structures represent a new material group. Within the design progress classical materials are replaced by these new class when a series of physical / mechanical requirements are touched. Typical requirements are related to strength, stiffness, electrical or thermal conductivity. In this study the vibration behaviour is looked at in detail. The overall objective is a description of the dynamic response by numerical simulation. An extraordinary detailed FEM model would exceed available resources. Therefore a proper model with special descriptions for the hollow spheres, the matrix material and the interconnections has to be defined. This paper provides a proper FEM model. Results are compared with vibrations measured by a laser scanning vibrometer.
