受到压应力的薄膜或层压材料可能会因涉及屈曲传播的机制而失效。当膜的破裂伴随着屈曲时，提供了用于分层的附加驱动力。这提供了一种机制，通过这种机制，裂纹可以隧穿压缩应力膜。虽然该过程的力学与以前的简单屈曲分析非常相似，但在这些早期分析所排除的条件下，同时发生开裂和屈曲的可能性允许发生分层。
Films or laminates subjected to a compressive stress may fail by a mechanism that involves the propagation of a buckle. An additional driving force for delamination is provided when cracking of the film accompanies the buckling. This provides a mechanism by which cracks can tunnel through compressively stressed films. Although the mechanics of the process is very similar to previous analyses of simple buckling, the possibility of concurrent cracking and buckling allows delamination to occur under conditions excluded by these earlier analyses.
