Abstract
In this paper, a Dual Reciprocity Boundary Element formulation for the so-
lution of free vibration problems of anisotropic continua is described. The
problems encountered with the fundamental and particular solutions are
explained and some questions regarding their choice and implementation
are answered. A three-dimensional numerical example is given by which
the influence of the internal collocation points on the representation of the
mass matrix and the occurrence of complex-valued eigenfrequencies is in-
vestigated. The results that are obtained for the eigenfrequencies and mode
shapes are compared to FE computations and excellent agreement is ob-
served.
