Abstract

In the design of windturbine blades composite beams are often used as the load bearing element. The beam is primarily subjected to bending moments, and the deformations are relatively large. The large displacements result in a kind of ovalization of the beam section, the so-called Brazier effect. The paper describes a simplified analysis of the Brazier stresses, and the results are compared with a full non-linear Finite Element analysis.
