Something is brittle when a very small failure propagates easily and becomes a large failure. The ductility of the adhesive layer in shear is the key property affecting the joint strength; the reference parameter is the ultimate adhesive shear strain energy, which is proportional to the toughness given by the area under the stress–strain curve (Hart-Smith, 1973a).In addition, ductility offsets the effect of shear and peel stress peaks. It doesn't have anything to do with changing the chemistry, so it's just a physical change. The ductile-to-brittle transition can be measured by impact testing: the impact energy needed for fracture drops suddenly over a relatively narrow temperature range – temperature of the ductile-to-brittle transition.
