Tóm tắt báo cáo

Guided wave propagation in an isotropic / transversely isotropic / orthotropic solid plate coupled with two fluid layers are discussed in this work. Suitable boundary conditions are applied at the free surfaces of fluids and the interfaces between the solid and the fluids to derive dispersion equations. Based on the equations, dispersion curves are obtained by numerical computation for several cases of study. Finally, we introduce explicit expressions of displacements and stresses in the trilayered structures.
