Environmental Effects on the Behaviour of Laminated Shells

Abstract

A higher-order shear deformation theory of elastic shells is developed for laminated shells, taking into account environmental effects on the behaviour of the shell such as the following: moisture, temperature, prestress and obviously normal charge at the shell surface. The shell model is based on a displacement field in which the displacements of the middle surface are expanded as cubic functions of the thickness coordinate, and the transverse displacement is assumed to be constant through the thickness. So, the distribution of shear deformation is parabolic and there is no need to use shear correction factors. Some numerical results are presented.
