Abstract
Dry adhesives utilizing the Van der Waals forces are the focus of many applications. Detachment phenomena are especially important to explore in this field. Most previous research was done using axisymmetric models. However, several important cases cannot be analyzed with this simplification. In this work, we build a 3D model to examine the classical “poker chip” problem. We analyze the propagation stability for detachments initiating at the edge of the chip. Novel stability maps are presented for the investigated non-axisymmetric cases. The effect of compressibility and propagation front shape are presented as well.
