Abstract

The applicability of linear elastic fracture mechanics (LEFM) to fracture of composites is examined by comparing fracture energy obtained from the Griffith criterion. This criterion is used rather than the compliance method owing to the failure of the latter to produce significant results because of the deviation from linearity of the load-deflection traces. The good agreement observed between fracture energies calculated from LEFM and from the Griffith criterion justifies the application of LEFM.
