Sun and Khaleel  optimized the static performance of the riveted joint
by increasing the rivet length.
Among the topics are the accumulation of fatigue damages for block-type loads with the use of material memory function, the influences of estimation methods of power spectral density function on the calculated fatigue life with the spectral method, monitoring the destruction process of material using a high-speed camera and a catodioptric stereo-vision system, shear strength testing of bonded joints of dental materials, and evaluating riveted joint
load-carrying capacity based on the formed rivet head dimension.
The chapters cover subjects such as structural design solutions and loading conditions for fuselage skin joins; relevance of laboratory test results for simple lap joining specimens to riveted joints
in a real structure; the effect of various production and design related variables on the riveted joint
fatigue behavior; theoretical and experimental analysis of secondary bending and its implications for riveted joint
fatigue performance; nucleation and shape development of fatigue cracks in riveted longitudinal lap joints; overview of experimental investigations into the multi-site damage for full-scale fuselage panels and riveted lap joint specimens; residual strength predictions for riveted lap joints in a fuselage structure.
pins and nylon washers between wings of pivot hinges are other quality signs.
In a presentation to the International Council of Aeronautical Sciences last year, Christner reported that in side-by-side tests, friction stir welded joints had two or more times the static strength of a comparable yet conservatively designed riveted joint
. Fatigue properties of stir welded joints were found to be at least as good as those of riveted joints
The riveted joints
could be used but since the plates are weakened at the joint due to the rivet holes the plate thickness should be enhanced by considering the joint efficiency.
Her research was on fatigue in the riveted joints
of the fuselage of aircraft.
Among the topics are inertia friction welding for aerospace applications, hybrid laser-arc welding of aerospace and other materials, heat-affected zone cracking in welded nickel superalloys, quality control and non-destructive testing of self-piercing riveted joints
in aerospace and other applications, composite-to-metal bonding, and high-temperature brazing.
