| description abstract | The pipes in offshore and marine structures are mainly made of lowstrength structural steels such as A537 steel and are subjected to the effects of both corrosive medium and cyclic loading caused by many factors. Reinforcement and repair of components using composite patches can be used for piping to reduce the stress intensity factors at the crackfront of a corrosion fatigue crack. In this paper 3D finite element analyses in general mixedmode fracture condition are performed to study the crack growth behavior of repaired pipes subjected to internal cyclic pressure. The required formulations, crack growth modeling, and remeshing are automatically handled by developing an ANSYS parametric design language (APDL) program. For this purpose an offshore pipe made of lowstrength steel containing an initial fatigue corrosion crack repaired by glass/epoxy composite patch is considered. A parametric study will be performed to find the effects of patch thickness on fatigue crack growth life extension and crackfront shape of the repaired pipes. | |
