Abstract (EN): This study aims to determine the mode I Stress Intensity Factor, K-I, for a steel alloy specimen extracted from a pressure vessel, so-called P355NL. The geometric and mechanical properties are derived from Compact Tension, CT, specimens available in the relevant literature. The theoretical value of K-I is evaluated through the formulation reported in ASTM E 647-15 ASTM International (Standard test method for measurement of fatigue crack growth rates. West Conshohocken, PA, 2015, [1]) for the geometric properties used in the previous study. Numerically, to solve the CT specimen problem, a Finite Element code software, ABAQUS (c) is used. Therefore, obtained numerical results are then compared to the theoretical ones, leading to assess the numerical analyses' performance. In this study, distinct crack lengths are considered as; a = {8, 9, ... , 20 mm}. Overall, encouraging results were obtained possessing a satisfactory agreement compared to theoretical solution.
