Abstract

The Boundary Element Method is combined with the Dual Reciprocity Method to analyse aging viscoelastic structures; the general theoretical formulation, the description of numerical algorithms and some examples are given. 1 Introduction The main advantage of the BEM derives from its capacity to solve completely a problem working only with values on the boundary. This advantage is somewhat diminished when the presence of body forces leads to domain integral that must be evaluated using internal cells. For situations in which the body forces derive form a potencial and are known beforehand (that is the case of body forces due to^ gravity, inertia, temperature), the Galerkin vector can be used, Brebbia et al.' However, the need to introd
