Analytical Modeling of Buckling Behavior of Porous FGM Cylindrical Shell Embedded within an Elastic Foundation

The aim of this paper is to investigate the buckling behavior porous Functionally Graded Materiel (FGM) cylindrical shells based on Donnell shell theory. In context, we develop an explicit analytical expression which takes into consideration effect porosities through thickness structure and that elastic foundation using a modified power-law function models Winkler Pasternak, respectively. We use rule mixture determinate FGM shell. effects porosity volume fraction, index, Young’s modulus ratio are investigated. Moreover, also discuss influence different parameters stability
