dc.description.abstract | In this paper, we propose a spectral element method (SEM) to study guided waves in coupled problems involving thin-walled
structures and fluid-acoustic cavities. The numerical method is based on the subdomain decomposition of the fluid-structure
system. Two spectral elements are developed to represent the fluid and the structure. A plate element based on a mixed ReissnerMindlin
and Kirchhoff-Love formulation is proposed to represent the thin-walled structure. This element uses C0 approximation
functions to overcome the difficulties to formulate elements with arbitrary order from C1 functions. The proposed element uses
a substitute transverse shear strain field resulting free shear locking. The fluid element is derived from the Helmholtz equation.
These elements use Lagrange polynomials as shape functions at the Legendre-Gauss-Lobatto (LGL) points. The analysis is carried
out by a two-and-a-half dimension (2.5D) approach in the wavenumber-frequency domain. The guided wave in a fluid cavity with
a flexible side is analysed. | es |
