This paper deals with the measurement of mode I interlaminar fracture toughness, Glc, of composite laminates by using double cantilever beam (DCB) specimens. It is shown that a formula commonly used for data reduction, based on linear elasticity, may result in small errors in calculating Glc, even when marked non-linearities in the load-displacement curve are observed, because of the adoption of thin samples. The implications of this finding for the design of the DCB specimen are discussed; furthermore, some experimental results are presented, for graphite/epoxy composites, which confirm theoretical predictions.
