This study analyzed the thermal vibration of functionally graded graphene platelets reinforced composite annular plate on an elastic foundation using the generalized differential quadrature method. Through a comprehensive parametric study, it was found that the temperature rise pattern and distribution of graphene platelets have a significant impact on the structure response.
In this article, the thermal vibration of functionally graded graphene platelets reinforced composite (FG-GPLRC) annular plate resting on an elastic foundation under the mechanical load framework of higher order shear deformation theory (HSDT) is analyzed. Governing equations and boundary conditions are established by employing Hamilton's principle. A generalized differential quadrature method (GDQM) is applied to obtain a numerical solution. Numerical results are compared with those published in the literature to examine the accuracy and validity of the applied approach. A comprehensive parametric study is accomplished to reveal the influence of stiffness of the substrate, patterns of temperature rise, temperature gradient, axial load, weight fraction and distribution patterns of GPLs, outer radius to inner radius ratio, inner radius to thickness ratio of the annular plate, and geometric dimensions of GPLs on the response of the structure. The results revealed that applying sinusoidal temperature rise and locating more square-shaped GPLs in the vicinity of the top and bottom surface result in the highest natural frequency.
