The authors present theoretical and experimental work in an effort to characterize the strength of adhesion forces between a thin elastomeric film bonded to a rigid surface and a flexible plate. The peel test is used to measure the adhesive forces: a spacer of known height is slipped between the flexible plate and the rigid surface, such that a crack forms between the adhesive and the flexible plate. The height of the spacer (<math> \Delta </math>) and the length of the crack (a) is used with other parameters to quantify the strength of the adhesive force, as a stronger adhesive should correspond to a shorter crack. The authors examine the limits of perfect adhesion and of perfect slippage.
