This thesis deals with the structural damage and its corresponding effect on the residual ultimate strength of seamless metallic pipes. The structural damage is here characterized as the type of damage produced by external mechanical interference, considerably undermining the strength and/or stability of the pipes. Not only the aesthetic...

Numerical investigation is conducted in this paper on both intact and dented seamless metallic pipelines (diameter-to-thickness ratio D/t around 21), deploying nonlinear finite element method (FEM). A full numerical model is developed, capable of predicting the residual ultimate strength of pipes in terms of bending capacity (M<sub>cr</sub>)...
