Knowing the strains and stresses in an adhesive joint is critical for the understanding and proper modeling of adhesive joints. To find a good method for measuring this has been a part of the work done by FP7 Co-Patch research program. Since the adhesive is sandwiched between the adherents the strains in the joint areas are difficult to measure. Movements of the entire joint can be measured with displacement transducers or crack opening can be measured with clip gauges. But these methods only allow an indirect evaluation of the conditions in the adhesive joint.
