Three-dimensional thermoelasticity analysis of graphene platelets reinforced cylindrical panel

Abstract

Thermoelastic behavior of composite cylindrical panel reinforced with graphene platelets distributed along the radial direction uniformly (UD) or functionally graded, FG−Δ, FG−∇, FG−⋄ and FG−X pattern is studied in the frame work of elasticity theory. Functionally graded graphene platelets reinforced composite (FG-GPLRC) cylindrical panel with simply supported boundary conditions is subjected to constant temperature at its inner and outer surfaces. By applying Fourier series expansion to the physical quantities along the axial and circumferential coordinates and using state space technique along the radial direction, state space governing differential equations can be derived and solved analytically. Parametric study is conducted by considering the effects of weight fraction as well as geometry and size of GPLs, pattern of graphene platelets distribution, applied temperature on thermoelastic behavior of GPLRC cylindrical panel. From numerical illustration it is evident that adding a little content GPLs affects thermoelastic behavior of GPLRC cylindrical panel significantly.
