This book reviewed forced vibrational behavior of porous nano-composite shells reinforced with graphene platelets, under radial dynamic loads. The geometry of a cylindrical shell with graded porosities and graphene platelets has been discussed in this book. Also, the type and distribution of exerted dynamic load to the shell. The material properties are dependent on the uniform, non-uniform distributions, and porosities. Description of the material properties of such nano-composites accounting for porosity and GPL content is performed via Halpin-Tsai micromechanical rule. The dynamic equations of the nano-composite shell are based on first order shell theory and a semi-analytical approach is implemented.
