Pipelines are critical infrastructure that plays an important role in the oil industry, and the most widely used mode of transportation in the world to transport gas and oil. One example is the proposed gas pipeline that will connect Nigeria with Morocco [1]. The external environment may impact these pipelines by scraping excavation equipment or rock causing damage in the form of a notch or crack in the wall of the pipe which consequently affects the resistance of the structures during their use. This requires knowledge of the degree of harmfulness of defects and its effect on the lifetime of pipelines. Based on this method, we intend to proceed by the use of the fracture mechanics. In this paper, we will use numerical simulation using ABAQUS software to describe the most important parameters of the rupture mechanics used to predict pipe rupture in the field of elastic mechanics. Analyzes existing in the literature. At the end of this paper, we computed the Stress Intensity Factor KI mode I in the elastic domain using the XFEM method integrated in ABAQUS. The results that we will develop later will show a good agreement between the results computed by the software ABAQUS and this one found by the analytical methods of several authors. |
