In this Chapter the modern application of the boundary element method to crack problems in dynamic fracture mechanics is reviewed. Dual boundary formulations are presented for the time domain, Laplace transform and dual reciprocity methods. The three approaches are applied to mixed mode two- dimensional and three-dimensional crack problems.
With reference to three-dimensional linear elastic solids susceptible to fracture processes, a symmetric Galerkin boundary element method is developed, based on the regularized version of the weak-form displacement and traction integral equations, and thus involving only kernels O(1/r). When the singularity is active, the numerical evaluation of the double surface integrals is carried out by using...
This chapter presents direct formulations of the boundary element method for the two-dimensional scattering of seismic waves from irregular topographies and buried valleys. The BEM models were formulated with isoparametric, quadratic boundary elements, and were employed to simulate a section of the Mexico City valley. Because the Mexico City valley is relatively flat and shallow, and the contrast...
