Large deflection analysis of functionally graded annular sector plates subjected to thermomechanical loads is presented. Based on the first-order shear deformation theory in conjunction with nonlinear von Kármán assumptions, the governing system of equations is derived. A polynomial-based generalized differential quadrature (GDQ) method is used to discretize the nonlinear governing equations. The Newton-Raphson algorithm is then employed to solve the system of nonlinear algebraic equations. Material properties of the plates are assumed to depend on temperature and are graded in the thickness direction based on a simple power-law distribution. Based on a comparison of results obtained for plates with temperature-dependent material properties versus plates with temperature-independent material properties, it is found that the effects of temperature dependency cannot be neglected. Furthermore, the effects of temperature rise, material index, thickness-to-radius ratio, and temperature dependency of material are studied in detail.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
