INTER RIVET BUCKLING PDF

In the elastic case, column-buckling (or critical) stress can be predicted using the Euler stringers that can experience inter-rivet buckling. Further details can be. This paper deals with the modelling of hybrid composites and is focused on a detailed simulation of the inter-rivet buckling behaviour in a stiffened fuselage shell.
