Abstract
Advanced layer-wise shells theories based on trigonometric functions expansions are considered to evaluate the static behavior of multi-layered, orthotropic shells. The aim of the present work is to extend the basis functions used for layer-wise formulation to a trigonometric basis functions properly defined. Carrera Unified Formulation for the modeling of composite shell structures is adopted. Via this approach, higher order, zig-zag, layer-wise and mixed theories can be easily formulated. The governing differential equations of the problem are presented in a compact general form. These equations are solved via a Navier-type, closed form solution. As assessment, results are compared with available exact solutions present in literature. ©2012 AIAA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
