    coupled thermoelastic response of functionally graded cylindrical shells by using galerkin method 
     
     this paper presents coupled thermoelastic response of cylindrical shells that made of functionally graded materials (fgms) under thermal heat flux. a secondorder shear deformation shell theory that accounts for the transverse shear strains and rotations is considered. the galerkin method approach is used to transform the governing equations into a set of linear ordinary differential equations. the resulting system of equations is solved through a numerical integration scheme the shell is graded through the thickness assuming a volume fraction of metal and ceramic, using a power law distribution.
    presented coupled thermoelastisty functionally gradedplates based on the third-order shear deformation theory. the present work deals with the coupled thermoelasticity problem of a titanium–zirconia functionally graded cylindrical shell under gas flow. the material properties are graded along the thickness direction according to a volume fraction power law distribution.the governing equations are based on the first-order shear deformation plate theory, including the rotary inertia term. the lord-shulman linear thermoelastic theory is considered, and the galerkin approach is used as a solution method.
