| Abstract |
A very large number of variables affect the response of bolted or riveted joints typically
used in aerospace applications: geometry of the joint, characteristics of the sheets, friction between
sheets, geometry of head and kind of fastener, amplitude of clearance before assembly, mounting
axial load, pressure effects after manufacture. It must be also recalled that these parameters
influence the many failure modes existing for such joints, among which a relevant importance is
attributed to bearing.
The present paper deals with the study of the influence of assembly parameters on the joint
operational behaviour and in particular with the analysis, performed through numerical simulations,
of the influence of the residual stress-strain state coming from the riveting operation on the bearing
resistance of an aluminium alloy joint.
This work has been developed within the FP6 research project called MUSCA (Non linear static
multiscale analysis of large aero-structures). |
