This paper discusses the calculation of the natural frequencies of thin structural compo-
nents using the Dual Reciprocity boundary element method.
This technique, introduced
by Nardini and Brebbia in 1982, has certain advantages over other boundary element
techniques in that it produces a linear, time independent, boundary only system which
is compatible with standard 'black box' eigenvalue solvers.
Results are presented which
provide comparison with theoretical approximations and show how the method behaves
for a more realistic application, a microstructure, for which finite element results are
Traditional integral equation formulations, involving the elastodynamic fundamental
solution, which is complex valued and frequency dependent...
