594 Sanjeev M Kavale et al. / Procedia Structural Integrity 14 (2019) 584–596 Sanjeev M. Kavale, Krishnaraja G Kodancha, Nagaraj Ekbote / Structural Integrity Procedia 00 (2018) 000–000 11 (57.50 √ ). The value of critical Stress Intensity Factor obtained through Eq. 5 is K I = 1979.302 √ (62.60 √ ). An error of 8.86% is observed between the experimental value and SIF obtained through formulation generated. On the similar lines polynomials generated for normalized T 11 and T 33 at the center of the specimen are shown in Eq. 6 and Eq. 7.
