Transient Thermal Stresses of Functionally Graded Thick Hollow Cylinder under the Green-Lindsay Model
ثبت نشده
چکیده
The transient thermoelastic response of thick hollow cylinder made of functionally graded material under thermal loading is studied. The generalized coupled thermoelasticity based on the Green-Lindsay model is used. The thermal and mechanical properties of the functionally graded material are assumed to be varied in the radial direction according to a power law variation as a function of the volume fractions of the constituents. The thermal and elastic governing equations are solved by using Galerkin finite element method. All the finite element calculations were done by using commercial finite element program FlexPDE. The transient temperature, radial displacement, and thermal stresses distribution through the radial direction of the cylinder are plotted. Keywords—Finite element method; Thermal stresses; GreenLindsay theory; Functionally graded material.
