We study the birth and propagation of a delamination front in the peeling of a soft, weakly adhesive layer. In a controlled-displacement setting, the layer partially detaches via a subcritical instability and the motion continues until arrested, by jamming of the two lobes. Using numerical solutions and scaling analysis, we quantitatively describe the equilibrium shapes and obtain constitutive sensitivities of jamming process to material and interface properties. We conclude with a way to delay or avoid jamming altogether by tunable interface properties.

分层前沿的受控传播和阻塞。

我们研究了在软弱粘合层的剥离中分层前沿的产生和传播。在受控位移的情况下，该层通过亚临界不稳定性部分剥离，并且运动持续进行，直到两个凸角卡住为止。使用数值解和缩放分析，我们定量地描述了平衡形状，并获得了干扰过程对材料和界面特性的本构敏感性。我们以一种可延迟的接口属性来延迟或完全避免阻塞的方式结束。
