Thermoelastic analysis of non-uniform pressurized functionally graded cylinder with variable thickness using first order shear deformation theory(FSDT) and perturbation method

摘要: Recently application of functionally graded materials(FGMs) have attracted a great deal interest. These materials are composed various with different micro-structures which can vary spatially in FGMs. Such composites varying thickness and non-uniform pressure be used the aerospace engineering. Therefore, analysis such composite is high importance engineering problems. Thermoelastic cylinder variable under considered. First order shear deformation theory total potential energy approach applied to obtain governing equations non-homogeneous cylinder. Considering inner outer solutions, perturbation series solve equations. Outer solution for out boundaries more sensitive at Combining near far points from leads accurate displacement field distribution. The main aim this paper show capability matched asymptotic cylinders shapes pressures. results design optimum also some properties as temperature residence by applying material.
