... of longitudinal specimens. Delaminations that were formed at inclusion sites during punching of the rivet holes and that were filled with nickel during the plating operation were revealed by microscopic examination of the rivet hole. These delaminations were interpreted to have acted as stress raisers...

... by a supplier. In less than one year, the panels began to delaminate and the aluminum began to crack. It was found that the failure was the result of chloride-induced intergranular corrosion caused by chemicals in the adhesive and excessive moisture in the wood introduced during manufacturing. Adhesive...
