摘要: A boundary-element scheme is proposed for the numerical determination of stress-strain state a three-dimensional composite body, which an elastic inclusion arbitrary shape perfectly bonded to infinite matrix. The involves reduction original problem six boundary integral equations components interfacial displacements and forces parametrization discretization these using generalized Gaussian integrals topological maps with regularizing Jacobians. Numerical results are obtained cylindrical rounded ends in matrix subject at infinity constant acting along this fiber. influence length-to-radius ratio fiber moduli on stresses examined
