Modifications were made in the well-known inherent flaw model as well as in the stress fracture models namely, point stress criterion and average stress criterion for accurate prediction of notched tensile and compressive strength of composite laminates containing holes. The adequacy of these modified fracture models were examined by considering the fracture data of center-hole specimens made of carbon/epoxy composites, weft-knitted glass fiber composites, and pultruded composites. Any one of these three fracture models can be utilized to predict the notched strength.
