Generation of Kitagawa - Takahashi type plots for SA 333 grade 6 ferritic steel

Based on the concept of Kitagawa-Takahashi plot, an attempt was made to generate different stress (S) - crack length (a) curves for a nuclear grade SA333 Grade 6 ferritic steel. These plots may be used for the prediction of stress levels for the material with different initial flaws to achieve the desired finite fatigue lives.
