    Abstract

    An inexpensive test method for evaluating the debond resistance of adhesive joints is described. A double-cantilever-beam specimen is used, and a strain gage is mounted on the unbonded portion of one adherend. When a fixed displacement is applied to the end of the specimen, the strain gage output along with the specimen compliance and the amount of fixed displacement at the end of the specimen are used to calculate the crack length, a, and the sustainable crack driving force, G, at the time the gage is read.
