Abstract
A peripheral crack in a steel rounded pipe beneath periodic bending loading is studied in this paper. The analysis of the fatigue crack growth is done in accordance with Paris law. The growth of fatigue crack is also analyzed with various initial crack “α” beneath periodic loading. The weight of the Paris exponent on fatigue crack propagation is presented as well. Furthermore, the “fatigue crack growth” progression of several specimens is evaluated experimentally by an invented setup. Conclusively, the experimentally achieved results are compared with the numerical results. This comparison demonstrates good compliance with the theoretical results.
