Calculation of the random-incidence scattering coefficients of a sine-shaped surface

Following the work of [12], in this article we extend the Arlequin method – originally developed in [4] (see also [23]) for static problem, in [24] and [25] for dynamic problems

As the problem size grows, direct solvers applied to coupled BEM-FEM equa- tions become impractical or infeasible with respect to both computing time and storage, even using

The purpose of this article is to propose the topological sensitivity field computed by means of the Fast Multipole BEM (FM-BEM) [16,17,27] as the basis of a computationally fast

In recent years, Fourier-based methods, originally introduced by [Moulinec and Suquet, 1994], have become ubiquitous for computing numerically the properties of composite

If we know a method to evaluate the integrals over the elements, and if the displacement discontinuity vector at each element (3 components) is known we can find using relation [3]

For the case of the sG or another nonlinear Hamiltonian equation, we justify the coupling conditions at the vertices of the network using a homothetic approach and conservation

Predictions of physical phenomena in buildings are carried out by using physical models formulated as a mathematical problem and solved by means of numerical meth- ods, aiming

Hybrid numerical method associating a conformal transformation of the complex plane with a matrix formulation for the calculation of the eigenvalues andeigenvectors in
