Pressure vessels are widely used in various industries, including petrochemicals, nuclear, and aerospace. However, these vessels are susceptible to crack formation, which can lead to catastrophic failure. A semi-elliptical surface crack is one of the most common types of cracks that can occur in pressure vessels. In this article, we investigate the behavior of a semi-elliptical surface crack in a pressure vessel using analytical and numerical methods. We perform a literature review on the topic and present our findings on the crack propagation behavior and the remaining life of the pressure vessel. Our results can aid in the analysis and assessment of pressure vessels with a semi-elliptical surface crack.
