- Abstract
Corrosion as well as cracks can lead to sudden and unexpected failure of materials, especially in pipelines used to transport gas under severe pressure and different temperatures. This article studies the effect of cracks and corrosion using the finite element method. Several sizes of cracks and corrosion have been studied. The damaged area theory was also applied and from the results obtained it was found that the damaged area ratio DR adhesive and the J integral increases with increasing corrosion and crack size (a / t). We can also conclude that the diamond shape is the best because it offers the smallest DR value compared to the other two (rectangular and circular.
