چکیده مقاله
The wave propagation of a functionally graded plate is studied using the first-order shear deformation plate theory.
Material graded properties are assumed in the thickness direction according to a simple power law distribution in
terms of the volume fractions of the constituents. Considering the effects of transverse shear deformation and rotary
inertia, the governing equations of the wave propagation in the functionally graded plate are derived by using the
Hamilton’s principle. The analytic dispersion relation of the functionally graded plate is obtained by solving an
eigenvalue problem. Numerical examples show that the characteristics of wave propagation in the functionally graded
plate are relates to the volume fraction index of the functionally graded plate. The influences of the volume fraction
distributions on wave propagation of functionally graded plate are discussed in detail. The results carried out can be
used in the ultrasonic inspection techniques and structural health monitoring.
