The simulation of 3D elastic scattering produced by thin rigid inclusions using...
Tadeu, António; Mendes, Paulo Amado; António, JulietaA mixed formulation that uses both the traction boundary element method (TBEM) and the boundary element method (BEM) is proposed to compute the three-dimensional (3D) propagation of elastic waves scattered by two-dimensional (2D) thin rigid inclusions. Although the conventional direct BEM has limitations when dealing with thin-body problems, this model overcomes that difficulty. It is formulated in the frequenc...
3D elastic wave propagation modelling in the presence of 2D fluid-filled thin i...
Tadeu, António; Mendes, Paulo Amado; António, JulietaIn this paper, the traction boundary element method (TBEM) and the boundary element method (BEM), formulated in the frequency domain, are combined so as to evaluate the 3D scattered wave field generated by 2D fluid-filled thin inclusions. This model overcomes the thin-body difficulty posed when the classical BEM is applied. The inclusion may exhibit arbitrary geometry and orientation, and may have null thicknes...
