摘要：

This paper is part of a research project concerning the efficiency of composite repair in corroded metallic pressure vessels. The focus is to evaluate localized repairs in corroded areas near nozzles. A numerical model was developed, and the results were validated against experimental tests. 50%, 70%, and 80% thickness reduction defects were manufactured into small-scale metallic vessels in two different positions and the failure pressure of the repaired vessels was determined using hydrostatic tests. The numerical and experimental results show that the failure pressure of the repaired vessel is close to the non-defective vessel, showing that the repair system was efficient.
