Abstract

This work shows the wave propagation in fluid-solid interfaces due to dynamic excitations, such interface waves are known as Scholtes waves. We studied a wide range of elastic solid materials used in engineering. The interface connects an acoustic medium (fluid) and another solid. [...]

Abstract

In this work, a hierarchical variant of a boundary element method and its use in Stokes flow around three-dimensional rigid bodies in steady regime is presented. The proposal is based on the descending hierarchical low-order and self-adaptive algorithm of Barnes-Hut, and it is [...]

Abstract

This work presents the results of the analysis of the one-dimensional advective diffusion equation from the Boundary Element Method. The developed formulation use a time independente fundamental solution and a transformation of the domain integral into weighted boundary values, [...]

Abstract

This work is focused on the finding of numerical results for detection and characterization of sub-surface cracks in solids under the incidence of Rayleighs elastic waves. The results are obtained from boundary integral equations, which belong to the field of dynamics of elasticity. [...]

Abstract

This paper presents a two-dimensional fast multipole boundary element method for large-scale analysis of anisotropic elastic problems. The expansions and fast multipole operations it uses are similar to those in formulations of fast multipole boundary element method already presented [...]
