Abstract
In this paper, using Creager and Paris's blunt elliptical hole stress distribution area equation, it is applied to crack and circular hole shaped defects using the theoretical radius value, which equalizes the maximum stress at the defect tip in terms of value to fracture toughness. By providing value equality, critical fracture stresses of all defect dimensions and tensile strength of the material were determined with a single mechanical test data. Compared with the predictions of other methodologies, it was determined that the obtained data gave results closer to the experimental values.
