Strengths Analysis of the Inner Deformation Carbon Steel Pipes by Finite Element Method

Fracture behaviors and strengths of pipes are very important for the integrity of vehicles, ocean structures, and so on forth. In pipes of vehicles and ocean structures, sometimes, the local wall thinning may result from severe erosion-corrosion damage. The elasto-plastic analysis is performed by FE code ANSYS on straight pipes with wall thinning. We evaluated the failure mode, fracture strength and fracture behavior from FE analysis. Also, the effect of the axial strain on deformations and failure modes was estimated by Finite element analysis. From the results, the fracture behaviors of pipes with the outer wall thinning were showed that can be applied to estimate the fracture behaviors of pipes with the inter wall thinning.
