Abstract In this study, a technique to predict the equivalent initial crack size (EICS) in a particulate composite material, containing hard particles embedded in a rubber matrix, was developed using constant strain rate crack propagation test data. The accuracy of the developed technique was determined. In addition, the statistical distribution of the equivalent initial crack size follows the second asymptotic distribution of maximum value.

In this study, a method is developed based on fracture mechanics, for predicting the equivalent critical initial crack size, aic in a particulate composite material. The predicted aic 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.
