The analytical model treats the uncracked region of the specimen as a Tapered Beam on generalized Elastic Foundation (TBEF), and the effect of crack tip deformation is incorporated in the formulation. A closed-form solution is obtained to compute the compliance and compliance vs. crack-length rate-change. The present TBEF model is verified with finite element analyses and experimental calibration data of compliance for wood-wood and composite-composite bonded interfaces. The compliance rate change can be used with experimental critical fracture loads to determine the respective critical strain energy release rates of interface bonds. The present analytical model can be accurately used for compliance and compliance rate-change predictions of TDCB specimens and reduce the experimental calibration effort that is often necessary in fracture studies.
