Abstract

The paper is focuses on the study of the profileoptimisation of a unidimensional structure inidealised critical flutter conditions. The problemhas been addressed already by other authors, buthere an original technique is used to search forsome variables at the left hand end of a simplysupported vibrating beam, the knowledge of which isnecessary for the numerical integration of thegoverning equations. Additionally, the frequency isconsidered as a control parameter. A compositeorthotropic symmetric panel with four layers isconsidered and the optimised profiles of all thestructural components determined.
