The Iosipescu shear test method, adapted for adhesives, was used to evaluate shear stress–strain properties of five epoxy‐based film adhesives. The shear strength of some adhesives, determined by this technique, was found to differ greatly from that determined by either lap shear and/or thick adherend tests. Accurate measurements of the adhesive bond‐line deformation enabled evaluation of the adhesive elastic and plastic properties as well as the calculation of shear modulus. A high‐speed video camera was employed to augment observation on the joint deformation.
