Abstract

The conventional tapered DCB specimen loaded at the apex is shown to exhibit less stability than parallel DCB testpieces cracking under stiff testing conditions. A modified test with loadings applied at the thick base instead of near the apex is suggested. Experiments agree with theory that this provides better cracking stability and easier control of the crack path, along with a wider range of crack velocities in one test.
