Displacements and stresses in pressurized thick FGM cylinders with exponentially varying properties based on FSDT

Thermo-elastic analysis of axially functionally graded rotating thick cylindrical pressure vessels with variable thickness under mechanical loading

“…They obtained the MLM is very suitable for the purpose of calculation of radial stress, circumferential stress, shear stress and radial displacement, but it is not useful for axial stress and not useful at all for axial displacement. Ghannad and Gharooni (2012) presented an elastic analysis and a closed form analytical solution for rotating FG thick walled hollow cylindrical shells subjected to constant internal and/or external pressure. They observed that FSDT method has acceptable results, but the radial and von Mises stresses resulted from FSDT show a significant difference by the results calculated from HSDT and FEM solution.…”
