In order to have a reasonable basis for ranking adhesive strengths in tensile tests, it is necessary to gauge the stress variations on the interface. In particular, the stress intensity there must be evaluated. This paper develops a path independent integral - the C-integral - to this end. The computational efficiency of the C-integral is demonstrated on a number of trial problems. These indicate that resolution is good, certainly sufficient to calculate stress intensities in actual engineering applications.
