Time harmonic and static crack problems in 3-D transversely isotropic bodies

Boundary Elements XXVI, ISBN 1-85312-708-6 Three dimensional crack problems in transversely isotropic solids under static and time harmonic dynamic loading conditions are studied in this paper using a mixed BE approach. Hypersingular and strongly singular kernels appearing in the formulation are regularized prior to any discretization. Two different crack geometries are studied. Stress Intensity Factors are computed from the crack opening displacements at quarter-point quadratic elements. The results obtained in this paper show a good agreement with other results. The number of elements required is rather small. Ministerio de Ciencia y Tecnología DPI2000-1217-C02-01 Ministerio de Ciencia y Tecnología DPI2001-2377-C02-01
