In this paper, a Dual Reciprocity Boundary Element formulation for the so-
lution of free vibration problems of anisotropic continua is described.
problems encountered with the fundamental and particular solutions are
explained and some questions regarding their choice and implementation
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-
The results that are obtained for the eigenfrequencies and mode
shapes are compared to FE computations and excellent agreement is ob-
Increasing use of anisotropic materials in engineering applications requires
efficient and accurate numerical methods for the s...
