A numerical approach for the solution of structural problems, based on the concept of parameter transfer finite elements, is here adopted to study the dynamic behaviour of composite wings. The purpose of this paper is to extend the methodology to a wing-like swept composite plate, which can be used, for example, for aeroelastic analysis, multidisciplinary optimization, structural control etc. The dynamics of composite swept wing is here analyzed and numerical results are compared with FEM solution. The effect of sweep angles and material anisotropicity on the aeroelastic behaviour of the wing is studied both from static divergency and dynamic flutter point of view. Several numerical results are presented.

Abstract
A numerical approach for the solution of structural problems, based on the concept of parameter transfer finite elements, is here adopted to study the dynamic behaviour of composite wings. The purpose of this paper is to extend the methodology to a wing-like swept composite plate, which can be used, for example, for aeroelastic analysis, multidisciplinary optimization, structural control etc. The dynamics of composite swept wing is here analyzed and numerical results are compared with FEM solution. The effect of sweep angles and material anisotropicity on the aeroelastic behaviour of the wing is studied both from static divergency and dynamic flutter point of view. Several numerical results are presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
