Evolution of a semidiscrete system modeling the scattering of acoustic waves by a piezoelectric solid
Thomas S. Brown, Tonatiuh Sánchez-Vizuet, Francisco-Javier Sayas
We consider a model problem of the scattering of linear acoustic waves in free homogeneous space by an elastic solid. The stress tensor in the solid combines the effect of a linear…
HDG methods for elastodynamics
Allan Hungria, Daniele Prada, Francisco-Javier Sayas
We derive and analyze a hybridizable discontinuous Galerkin (HDG) method for approximating weak solutions to the equations of time-harmonic linear elasticity on a bounded Lipschitz…
A Time-Dependent Wave-Thermoelastic Solid Interaction
George Hsiao, Tonatiuh Sanchez-Vizuet, Francisco-Javier Sayas +1
This paper presents a combined field and boundary integral equation method for solving the time-dependent scattering problem of a thermoelastic body immersed in a compressible, inv…
Boundary-Finite Element discretization of time dependent acoustic scattering by elastic obstacles with piezoelectric behavior
Tonatiuh Sanchez-Vizuet, Francisco-Javier Sayas
A coupled BEM/FEM formulation for the transient interaction between an acoustic field and a piezoelectric scatterer is proposed. The scattered part of the acoustic wave is represen…
A fully discrete BEM-FEM scheme for transient acoustic waves
Matthew E. Hassell, Francisco-Javier Sayas
We study a symmetric BEM-FEM coupling scheme for the scattering of transient acoustic waves by bounded inhomogeneous anisotropic obstacles in a homogeneous field. An incident wave…
