The adhesion problem for a microstructure with dimples

In this paper, we discuss an adhesion problem of double clamped beams with some 'dimples' on the surface. We also derive some formulas for designing the dimensions of the dimples and the length of beams. On beams, the adhesion is dominated by the dimension of the center dimple, and the maximum length of beams which do not adhere to their substrate decreases with the inverse cube of the dimple.
