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 ... -
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 ...
