A method has been developed involving combined numerical and experimental techniques to evaluate interlaminar fracture toughness (KIC) of the double cantilever beam specimen with slender cantilevers. Using FEM, a relationship is developed between the critical stress intensity factor and strain at a point near the crack tip. The strain is measured through a strain gauge of 0.2 mm gauge length. The location and the orientation for the strain gauge are optimized by the numerical analysis. Experiments were conducted on a DCB specimen prepared by bonding two thin plates of a hardened steel alloy. KIC of the interlaminar crack was determined by (i) the combined numerical and experimental technique knowing the strain near the crack lip and (ii) the numerical method knowing the loads at the cantilever ends. The experimental results were found to be within 18% of the predicted values.
