Notes:
Interfacial stress distribution of bonded quarter-planes subjected to a concentrated forcewas re-investigated based on Bogy’s solution[1]. The characteristic length of the singular interface end,δ, was defined, and found varying in a very large size scale with the index of stress singularity frommillimeter to nanometer or even smaller scale. The influences the characteristic length scale on theinitial debonding of the interface end is a new question worth to pay attention. Photoelasticityexperiment was employed to verify whether the initial debonding is always located at interface endwith stress singularity. The test results show that the initial debonding does not start from singularinterface end if the index of stress singularity is small enough
