Abstract

Moiré interferometry was utilized to study mode I interlaminar fracture in double cantilever beam specimens of unidirectional carbon fiber/epoxy composites. The crack opening displacement was experimentally determined in the vicinity of the crack tip to evaluate the distortion at the beam root of the specimen. The beam root distortion was found to make an important contribution to increasing the value of crack opening displacement. The effect of the beam root distortion on the evaluation of fracture toughness value was also examined.
