Historical Review on the Linear and Nonlinear Damped Structural Behavior of Composite Structures

Abstract

The present chapter describes the work reported in the area of structural analysis and structural dynamics of composite blade structures. Emphasis is given in the literature survey on analytical beam finite element models which assume linear kinematic assumptions in the constitutive equations. The effect of material coupling terms both in stiffness and damping structural matrices is also presented in the following paragraphs. However, the maximization of wind-turbine blades performance through longer rotor blades in combination with the development of new more flexible helicopter blade designs made the development of new nonlinear models essential regarding their structural analysis.
