“…The control volume element (CVE) for homogenization usually has to contain many hundreds or even many thousands of fibers and the distances between the fibers are small compared to their length even for small percentage of volume of the fibers in the CVE, the interaction of fibers is very strong and important and the physical fields in all matrix and fibers have large gradients. Iterative procedure, which is very effective also for materials reinforced by particles with small aspect ratio [7] with parallelization of computational strategy, is assumed. In the first step, it is supposed that fibers are rigid/very stiff in the fiber direction and their bending stiffness is negligible.…”

Composite materials reinforced by short fibres are considered to be the materials of the future because of their excellent electro-thermo-mechanical properties, when the fibres have much higher stiffness and thermal and electric conductivity than the matrix. Usually the aspect ratio of fibres is very high. The classical numerical methods cannot accurately simulate the interaction of fibre–fibre–matrix for complicated topology of such materials. The current paper presents a method that enables such problems to be solved efficiently and accurately for an elastic matrix with such inclusions. The method uses one-dimensional continuously distributed source functions (forces, dipoles and couples) along the fibre axis to simulate interaction of the fibre with matrix and neighbour fibres. Numerical results indicate the importance of the topology of reinforcing fibres (i.e. if the fibres are straight, imperfect straight or curved; if they are unidirectional; how they are distributed in the matrix) for the overall effect in the composite. Numerical results of the method are discussed.
