A boundary element method formulation is developed and validated through the solution of problems governed by the diffusion-wave equation, for which the order of the time derivative, say α, ranges in the interval (1, 2). This fractional time derivat

This work presents a boundary element method formulation for the solution of the anomalous diffusion problem. By keeping the fractional time derivative as it appears in the governing differential equation of the problem, and by employing a Weighted R

The main contribution of this work is the development of two Boundary Element Method (BEM) formulations for the dynamic analysis of Euler-Bernoulli continuous beams. The first one employs the static fundamental solution; due to this, it is named D-BE

This work presents a boundary element method formulation for the solution of the diffusion–advection problem. The formulation, developed for two-dimensional problems, for non-isotropic media, considers a spatially variable velocity field. The only

A Boundary Element Method formulation is developed for the solution of the two-dimensional diffusion-wave problem, which is governed by a partial differential equation presenting a time fractional derivative of order α, with 1.0 < α < 2.0. In the p

A boundary element method (BEM) formulation is developed for the analysis, in the time-domain, of the diffusion–advection problem for non-isotropic materials in two dimensions. As the diffusion–advection equation describes, among others, the poll
