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. Inter-rivet buckling of stiffener flanges fastener spacing, s. • flange under compression buckles with a half-wave length equal to the fastener spacing. • fasteners.

Receive monthly updates on new spreadsheets, additions to the Technical Library, Market News and Information, exclusive content and more. Wrinkling is a skin buckle that continues through a stiffener attach flange possibly to the adjacent panel, the behavior is mostly driven by rivet spacing and the distance between the rivets and an upstanding stiffener web.

The problem with oil-canning is [generally speaking], fatigue cracking at periphery fastener holes due to the large number of oil canning cycles per flight [which are not usually heard].
