THE EFFECT OF STRESS DISTRIBUTION ON THE FATIGUE BEHAVIOR OF ADHESIVE BONDED JOINTS.

Abstract

A study was made of the fatigue behavior of three types of 2024-T3 aluminum alloy adhesive bonded joints, single lap-joint, scarf-joint and butt-joint, bonded with two kinds of adhesives, a vinyl-phenolic type-FM 47 and a nitride rubber-phenolic type-Metlbond 4021. It was found that the different modes of fatigue failures of the single lapjoints, that is, sheet metal failure, and adhesive bonding failure, were caused by the different stress components in the joint. The influence of the variation of stress distribution caused by the difference in mechanical properties of the adhesive, geometry of the joints, and the type of loading on fatigue strength of the adhesive bonded joints, were analyzed.
