Abstract
An apparatus for improving and increasing sustainable shear force capabilities at an interfacing surface between a rigid material and a flexible material is disclosed. The interface includes at least two superimposed components having different surface roughnesses. A coarse surface roughness component has a surface roughness about 3 orders of magnitude greater than that of a fine surface roughness component. The interface is useful for all types of devices with a rigid-to-flexible interface that needs to resist shear, tension, torsion, compression, or any disturbing steady-state or variable force or forces.
