The welded joints are often dimensioned over one given lifetime while following an approach of the type S-N on the basis of acceptable probability of failure which should not be exceeded over the base period. The cracks induced by the welding process

Numerical model for estimating time-dependent reliability of a corroding pipeline over its lifetime

Autor: Mourad Nahal, Rabia Khelif

Publikováno v: International Journal of Advanced Structural Engineering, Vol 11, Iss 1, Pp 1-7 (2018)

This work aims to evaluate time-dependent reliability of a pipeline under corrosion impact over its lifetime. A finite element corrosion model was proposed, and an empirical power low model is also used and coupled with a probabilistic model for eval
