结果表明，当橡胶状聚合物薄膜以小角度从光滑玻璃表面剥离时，界面位错可以自发形成。这些位错的作用是阻止剥离，从而显著增加粘合接头的强度。理论分析表明，这种位错的结果从剥离的组合，其中的表面分离和愈合的表面自然走到一起，并重新构成的联合作为剥离机构之间的表面吸引力的结果。正是这种自发愈合，实验表明，表现出一个奇怪的时间衰减，这决定了剥离位错的形成和几何形状。
It is demonstrated that interfacial dislocations may be formed spontaneously when a thin film of rubbery polymer is peeled from a smooth glass surface at a low angle. The effect of these dislocations is to stop the peeling, thereby significantly increasing the strength of the adhesive joint. Theoretical analysis shows that such dislocations result from a combination of peeling where the surfaces separate and healing where the surfaces naturally come together and reconstitute the joint as a consequence of the surface attractions between the peeled bodies. It is this spontaneous healing, shown experimentally to exhibit a curious time decay, which determines the formation and geometry of the peel dislocations.
