Axisymmetric thermoelastic analysis of long cylinder made of FGM reinforced by aluminum and silicone carbide using DQM

چکیده مقاله

In this study, the thermoelastic stress analysis of a thick-walled cylinder made of functionally graded material (FGM) is investigated. The FGM is assumed a mixture of aluminum and silicone carbide in which the effective material properties are estimated through modified mixture law. Temperature distribution is obtained using the solution of one-dimensional heat transfer equation with the assumption of boundary condition. Solution procedure is developed based on the differential quadrature method. Effect of FGM characteristics such as percentages of ceramic particles at the outer side of cylinder's wall, and power of ceramic particles distribution, on the distribution of stress components, and temperature along the thickness are presented. In addition, stress distribution arising from the thermomechanical loading on structure, along the thickness are is investigated. Verification of the method, formulation and solution procedure is confirmed through comparison with available results in literature.
