Mantari, J.L. e Guedes Soares, C. (2014) , “Static response of advanced composite plates by a new non-polynomial higher-order shear deformation theory”, International Journal of Mechanical Sciences, Vol. 78, pp. 60-71

The static responses of functionally graded plates are investigated by using a recently developed higher order shear deformation theory (HSDT), which is also compared with other HSDTs available in the literature. A practical generalized numerical code for solving all the plate governing equations (formulated based on different HSDTs) is utilized. The mechanical properties of the plates are assumed to vary in the thickness direction according to a power-law distribution in terms of the volume fractions of the constituents. The plate governing equations and boundary conditions are derived by employing the principle of virtual work. Navier-type analytical solution is obtained for FG plates subjected to transverse bi-sinusoidal and distributed loads for simply supported boundary conditions. Results are provided for thick to thin FG plates and for different volume fraction distributions. The accuracy of the present code is verified by comparing it with various HSDTs available in the literature. Results show good agreement between the HSDTs for normal and transversal displacements, normal stresses and in-plane shear stresses. However, opposite occurs for transverse shear stresses.
