Blister tests are used to investigate the size effect on the critical energy release rate for the onset of debonding of interfaces between commercial tape and plain steel. The measured data display a size effect if the interfacial friction is not taken into account. A proportional displacement model is thus proposed to simultaneously evaluate the critical energy release rate and the frictional parameter. Theory and experiment give a critical energy release rate of 1.9956 Pa m for the onset of interfacial debonding between the commercial tape and the plain steel and it is independent of the blister size.
