دراسة نظرية لنمو شقوق الكلل لسبيكة الفولاذ المقاوم للصدأ باستخدام معادلة باريس المعمم

Abstract EN

A theoretical study was done in this work for Fatigue , Fatigue Crack Growth (FCG) and stress factor intensity range for steel.

It also includes Generalized Paris Equation and the fulfillment of his equation which promises that there is a relation between parameters C and n.

Usig Simple Paris Equation through which we concluded the practical values of C and n and compared them with the theoretical values which have been concluded by Generalized Paris Equation.

The value of da / dN and ΔK for every material and sample were concluded and compared with the data which was used in the computer program for the whole of our research .

The program is written in Fortran .

The theoretical and practical data was drawn with (Graf) program so as to conclude the data mentioned in the research.
