Abstract
A boundary integral formulation of the linear elasticity problem for a multi-component composite is given. The fast BEM solver based on the adaptive cross approximation is then obtained by the data-sparse representation of the resulting Galerkin matrices. The solver is used to obtain effective elastic moduli of fibre and particle reinforced composites in three dimensions by means of the strain energy equivalence principle.
