Abstract

Fracture behaviors and strength of pipes with local wall thinning are very important Jar the integrity of energy plants. In pipes of energy plants, sometimes, the local wall thinning may result from severe erosion-corrosion damage. Recently, the effects of local wall thinning on strength and fracture behaviors of piping system have been well studied. In this paper, the elasto-plastic analysis is performed by FE code ANSIS. We evaluated the failure mode, fracture strength and fracture behavior from FE analysis.
