Abstract

Inspired by the attachment ability of insects with smooth pads to vertical walls and ceilings, the mechanics of detachment of a rigid solid from an elastic wavy surface has been analyzed for the axisymmetric case of a sphere and the plane strain case of a cylinder [1]. Due to the qualitative similarities, the discussion was limited to the axisymmetric case only. The load-displacement curve for a sphere indenting a wavy flat surface is shown in Fig. 1, in which the load P is normalized with the JKR pull-off force P jxr and the approach displacement h is normalized with the waviness amplitude λ.
