Abstract

The fundamental aspects of fatigue fracture mechanisms (crack onset and propagation) in riveted single shear lap joints of fibre-metal laminate have been disclosed through extensive failure analysis of double-riveted 2/1 Glare (TM) laminate layup. Three fatigue fracture mechanisms, namely, rivet fracture, Glare laminate cracking and fretting fatigue have been determined as function of the peak stress. The roles of the joint elements and fibre-metal laminate constituents on the fatigue strength have been determined. Aligned riveting has shown more fatigue resistant than non-aligned rivets due to its higher restriction to secondary bending moments, so that potential fracture mechanisms were postponed and/or prevented. It has been discovery that, more than damage tolerance capacity, damage resistance capability determines the joint fatigue strength. The obtained results can provide insights in designing multi-rivet Glare joints with superior fatigue performance. (AU)
