Energy-based low cycle fatigue indicator prediction of non-load-carrying cruciform welded joints
Song, Wei; Liu, Xuesong; Berto, Filippo; Razavi, Seyed Mohammad Javad (Journal article, 2018)A new uniform analytical formulation is proposed to predict the low cycle fatigue assessment indicator of non-loading cruciform welded joints under tensile cyclic loading considering the effects of plasticity and mechanical ... -
Fatigue assessment of steel load-carrying cruciform welded joints by means of local approaches
Song, Wei; Liu, Xuesong; Razavi, Seyed Mohammad Javad (Journal article, 2018)In this paper, local approaches are employed to analyse stress distributions, local fatigue indicators of weld toe, and weld root in load‐carrying cruciform welded joints (LCWJs). An extension of previous available equations ... -
Fatigue crack growth behavior of Ni-Cr-Mo-V steel welded joints considering strength mismatch effect
Song, Wei; Wang, Ping; Wan, Di; Qian, Guian; Correia, José; Berto, Filippo (Peer reviewed; Journal article, 2021)High strength steel welded joints are usually fabricated by heterogeneous weld metal for reducing the negative impacts of microstructural characteristics and defects on mechanical properties, such as hydrogen embrittlement ... -
Localized wrinkling of metal films on elastic and liquid substrates
Sun, Yi; Yan, Liping; Chen, Benyong; Song, Wei; Berto, Filippo (Peer reviewed; Journal article, 2019)Global and localized wrinkling phenomena in films/substrates have been widely studied by means of experiment and theoretical analyses in the past two decades. They have shown broad application prospect in microstructure ... -
Low cycle fatigue life prediction of 10CrNi3MoV steel and undermatched welds by damage mechanics approach
Song, Wei; Liu, Xuesong; Xu, Jie; Fan, Yu; Shi, Duanhu; Yang, Feng; Xia, Xiaolei; Berto, Filippo; Wan, Di (Peer reviewed; Journal article, 2021)Welding of steel is a technique frequently used in practical engineering applications; however, their mechanical performance is strongly dependent on the physical metallurgical status of the weldments. In the present study, ... -
Low-cycle fatigue behavior of 10CrNi3MoV high strength steel and its undermatched welds
Song, Wei; Liu, Xuesong; Berto, Filippo; Razavi, Seyed Mohammad Javad (Journal article; Peer reviewed, 2018)The use of high strength steel allows the design of lighter, more slender and simpler structures due to high strength and favorable ductility. Nevertheless, the increase of yield strength does not guarantee the corresponding ... -
Modelling of fracture toughness of x80 pipeline steels in dtb transition region involving the effect of temperature and crack growth
Xu, Jie; Song, Wei; Cheng, Wenfeng; Chu, Lingyu; Gao, Hanlin; Li, Pengpeng; Berto, Filippo (Peer reviewed; Journal article, 2020)This work presents an investigation of the effects of temperature and crack growth on cleavage fracture toughness for weld thermal simulated X80 pipeline steels in the ductile-to-brittle transition (DBT) regime. A great ... -
Numerical Investigation of Strength Mismatch Effect on Ductile Crack Growth Resistance in Welding Pipe
Su, lin; Xu, Jie; Song, Wei; Chu, Lingyu; Gao, Hanlin; Li, Pengpeng; Berto, Filippo (Peer reviewed; Journal article, 2020)The effect of strength mismatch (ratio between the yield stress of weld metal and base metal, My) on the ductile crack growth resistance of welding pipe was numerically analyzed. The ductile fracture behavior of welding ...
