Abstract:

Fracturing characteristics of adhesive joints are investigated. Cracking in elevated temperature water is studied. The effect of testing temperatures down to -321 F on the toughness of joints was also evaluated. The effect on toughness of loading at rates up to those that causes the crack to approach its critical velocity, and corrosion fatigue of joints in a water environment were also investigated. Modified epoxy adhesives were studied.
