Abstract : Test techniques were developed to determine adhesive properties in tension and shear. These properties are directly usable in joint analysis methods developed to predict the load response of adhesive bonded joints. The test techniques employ a Tuckerman optical strain gage combined with a physitech optical tracker. It provides a recording of ten to the minus 6th power inches displacement with strain rate control and continuous recording capability. Modified epoxy with a supporting mat of polyester, epoxy/phenolic, and thermosetting rubber phenolic film adhesives were tested to demonstrate the suitability of the test techniques for use on all adhesive systems. The effects of bond thickness, bond width, strain rate, and adherend material on adhesive properties were investigated. A Ramberg-Osgood relation was found to describe the stress-strain behavior of adhesives. (Author, modified-PL)
