A review of functionally graded thick cylindrical and conical shells

Thick shells have attracted much attention in recent years particularly thick shells made from smart and graded material because of their unique properties. In this review paper, some critical issues and problems in the development of thick shells made from functionally graded piezoelectric material (FGPM) are discussed. This review has been conducted on various types of methods which are available for thick shell analysis and mainly focuses on elasticity theories, shear deformation theory, simplified theories and mixed theories since they were widely used in the modeling of FG thick shells. It is expected that this comprehensive study will be very beneficial to everyone involved or interested in the shell models
