Cai, J. (author), Jiang, X. (author), Lodewijks, G. (author), Pei, Zhiyong (author), Zhu, Ling (author)The ultimate strength of metallic pipelines will be inevitably affected when they have suffered from structural damage after mechanical interference. The present experiments aim to investigate the residual ultimate bending strength of metallic pipes with structural damage based on large-scale pipe tests. Artificial damage, such as a dent,...journal article 2019

Cai, J. (author), Jiang, X. (author), Lodewijks, G. (author), Pei, Zhiyong (author), Wu, Weiguo (author)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>)...journal article 2018

Cai, J. (author), Jiang, X. (author), Lodewijks, G. (author), Pei, Zhiyong (author), Wu, Weiguo (author)The combination damage induced by mechanical interference, in reality, is more likely to happen. In this paper, numerical models on pipes with combined dent and metal loss in terms of a notch are developed and validated through tests (diameter-to-thickness ratio D/t of test pipes around 21), capable of predicting the residual ultimate...journal article 2018

Cai, J. (author), Jiang, X. (author), Lodewijks, G. (author), Pei, Zhiyong (author), Wu, Weiguo (author)On the basis of an experimental investigation [1], numerical investigation is conducted in this paper on damaged seamless metallic pipelines with metal loss (diameter-to-thickness ratio D/t around 21) through nonlinear finite element method (FEM). Numerical models are developed and validated through test results by using the measured material...journal article 2018
