On the thermal analysis of 2-D temperature-dependent functionally graded open cylindrical shells

Abstract

Based on third-order shear deformation plate theory of Reddy, this paper presents thermoelastic response of a 2-D functionally graded open cylindrical shell (2-D FGM OCS) with temperature-dependent material properties. Taking into account temperature-dependent properties, the material properties of 2-D FGM OCS are assumed to be graded in radial and axial directions simultaneously according to a brand-new 2-D power-law distribution. Using the 2-D power-law distribution, it is possible to consider various kinds of two directional volume fraction profiles including sigmoidal radial variation as well as symmetrical or classical variation in axial direction. The non-linear steady-state heat conduction equation is solved using an iterative solution procedure along with generalized differential quadrature method (GDQM). In the mechanical analysis, the temperature field obtained from the thermal analysis is entered into the governing equations of the 2-D FGM OCS as a thermal loading. Detailed parametric studies shed new light on the influences of both various volume fraction profiles and variation of the material properties with temperature on temperature field and thermal stresses of 2-D FGM OCS. The present realistic study makes it a useful tool that will enable engineers to develop 2-D FGM OCSs with superior properties.
