Two-dimensional thermoelastic analysis of FG cylindrical shell resting on the Pasternak foundation subjected to mechanical and thermal loads based on FSDT formulation

چکیده مقاله

Two-dimensional thermoelastic analysis of functionally graded thick-walled cylinder is investigated under thermal and mechanical loadings and based on the Pasternak foundation. The rst-order shear deformation theory is used to describe the displacement eld. Fundamental governing di erential equa- tions of system are obtained by energy method and Euler equations. E ect of gradation of material properties and Pasternak foundation parameters are considered as important results of this study. The obtained results indicate that the end supports have considerable e ect on the longitudinal distribution of components. Furthermore, it can be concluded that with increasing the non- homogeneous index, both radial and axial displacements decreases.
