Fig. 10. Peel-force vs. rate of peeling for an elastomeric layer adhering to a polyester film. C and I denote cohesive and interfacial failure modes, respectively (101). To convert kN/m to ppi, divide by 0.175.

We note that equation (18) does not contain the size of the debonded zone. Shearing detachment is therefore predicted to take place at a constant force that depends on the elastic modulus and thickness of the adhering layer but not on the length of the bonded region or on the extent of debonding. These features have been verified experimentally for adhering elastomeric layers (137), and the theory has been extended to deal with short overlaps, when bending deformations become important (137), with adherends of unequal thickness (137), and with...
