研究表明，通过在粘接界面引入位错可以强化粘接接头。实验搭接剪切接头是由橡胶板制成的，在界面上制造了连续体型的位错。这些位错不是在原子水平上研究的，而是在强度测试中显示出来的，以影响打破粘接接头所需的力。通过研究搭接接头的失效机理，发展了描述这种断裂的Griffith断裂模型，并将该理论应用于含有界面位错的粘接接头的情况，从理论上解释了这一现象。
Abstract It is demonstrated that an adhesive joint may be strengthened by introducing dislocations into the adhesive interface. Experimental lap shear joints have been made from rubber sheets, dislocations of the continuum type being manufactured at the interface. These dislocations were not investigated at the atomic level but were shown in strength tests to influence the force required to break the adhesive joint. The phenomenon has been explained theoretically by examining the mechanism of failure of lap joints, developing the Griffith model of rupture to describe such fracture and by applying this theory to the case of an adhesive joint containing interfacial dislocations.
