The Application of Fracture Mechanics to Predict the Critical Initial Crack Length

Abstract

In this study, a method is developed based on fracture mechanics, for predicting the equivalent critical initial crack size, a(ic) in a particulate composite material. The predicted a(ic) is the crack size that should be used to develop an inspection criterion to determine the reliability of a structure made of the particulate composite material.
