Abstract

The analytical treatment of propagation of ultrasound in thick layers of fiber-reinforced composites simplifies greatly when the characteristic length scales of the propagating signal are much larger than the diameters of fibers and the thicknesses of plies. The inhomogeneous composite may then be modeled as a homogeneous but anisotropic solid. To investigate scattering of ultrasound by discrete flaws or regions of damaged material in such an effectively homogeneous solid it is convenient to formulate boundary integral equations and to solve these equations by the boundary element method. This formulation, is, however, based on basic singular solutions which for anisotropic solids are difficult to obtain in sufficiently simple form.
