Determination of Equivalent Initial Flaw Size in a Particulate Composite Material

Abstract

In this study, a method for determining the initial flaw size in a particulate composite material is developed. The results of analyses indicate that the initial flaw length and the critical flaw size follow the second asymptotic distribution of maximum value. It also indicates that on the first approximation, it can be assumed that the initial flaw size and the critical flaw size is independent of specimen thickness.
