• Determining critical CTOA from energy-load curves with DWTT specimen 

      Shuai, Jian; Tu, Shengwen; Wang, Junqiang; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Journal article; Peer reviewed, 2017)
      Running ductile fracture is one of the most catastrophic accidents of pipelines for natural gas transportation. Crack arrest toughness is important for preventing crack extension to a long distance along pipeline. Critical ...
    • A method for determining the ductile damage parameters of high strength steels and weld metal 

      Wang, Xu; Shuai, Jian; Ren, Wei; zhang, tieyao; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2023)
      The microvoid based Gurson-Tvergaard-Needleman (GTN) model is a powerful tool for predicting ductile fracture behavior, and application of such model to steels and welds needs the identification of microvoid related damage ...
    • Numerical study on the strain capacity of girth-welded X80 grade pipes 

      Wang, Xu; Shuai, Jian; Zhang, Sheng-Zhu; Ren, Wei; Zhu, Xue-Ming (Peer reviewed; Journal article, 2022)
      Strain capacity is an important performance indicator for designing and evaluating high-grade steel pipelines. Due to the inhomogeneity of material properties in welded structures, girth welds are one of the main factors ...
