Abstract In order to combine the lightweight and the stiffness of aeronautic structures in spite of their large size, they are built up by assembling many parts, one or two dimensions of which are much smaller than the others (beam, shells). As a consequence, assembling processes are difficult because of the flexibility of the parts. They can bend out under their own weight, which makes it necessary to use a lot of equipment, assembling jigs and clamping fixtures. Furthermore, many parts must be bent by clamping action before being assembled with fasteners. These assemblies have a… More >
