An asymptotically exact first-order shear deformation theory for functionally graded plates

We are happy to announce that Prof. Dr. hab Le Khanh Chau and colleagues recently published their work entitled "An asymptotically exact first-order shear deformation theory for functionally graded plates" in the International Journal of Engineering Science.

Abstract:

An asymptotically exact first-order shear deformation theory for functionally graded elastic plates is derived using the variational-asymptotic method. As an application, an analytical solution to the problem of wave propagation in a sandwich plate is found in accordance with this refined theory. Comparison between the dispersion curves obtained by 2-D plate theory and 3-D elasticity theory reveals that the former is accurate up to the order of h^2/l^2, where h is the plate thickness and l the wavelength.
