Abstract

In this work, refinements of classical theories are proposed in order to analyze isotropic, orthotropic and laminated plates and shells. Higher order theories have been implemented according to the Carrera Unified Formulation (CUF) and, for a given problem, the effectiveness of each employed generalized displacement variable has been established, varying the thickness ratio, the orthotropic ratio and the stacking sequence of the lay-out. A number of theories have therefore been constructed imposing a given error with respect to the available ’best solution’. The results have been restricted to the problems for which closed-form solutions are available. These show that the terms that have to be used according to a given error varies from problem to problem, but they also vary when the variable that has to be evaluated (displacement, stress components) is changed.
