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

Chúng tôi vui mừng thông báo rằng GS.TSKH Lê Khánh Châu gần đây đã xuất bản công trình của họ có tựa đề "An asymptotically exact first-order shear deformation theory for functionally graded plates" trên tạp chí International Journal of Engineering Science.

Tóm tắt:

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.
