• Hydrogen informed Gurson model for hydrogen embrittlement simulation 

      Yu, Haiyang; Olsen, Jim Stian; Alvaro, Antonio; qiao, lijie; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2019)
      Hydrogen-microvoid interactions were studied via unit cell analyses with different hydrogen concentrations. The absolute failure strain decreases with hydrogen concentration, but the failure loci were found to follow the ...
    • A microstructure informed and mixed-mode cohesive zone approach to simulating hydrogen embrittlement 

      Lin, Meichao; Yu, Haiyang; Wang, Xu; wang, ruijun; Ding, Yu; Alvaro, Antonio; Olden, Vigdis; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2022)
      Hydrogen induced failure under uniaxial tension is simulated in a duplex stainless steel considering microstructural feature of the material. There are three key ingredients in the modelling approach: image processing and ...
    • A predictive model unifying hydrogen enhanced plasticity and decohesion 

      Lin, Meichao; Yu, Haiyang; Ding, Yu; Wang, Gang; Olden, Vigdis; Alvaro, Antonio; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2022)
      The detrimental effect of hydrogen on metals which manifests itself as a transition from a ductile to a brittle failure mode is, for the first time, incorporated into a unified continuum-scale predictive framework. The ...
    • Simulation of ductile-to-brittle transition combining complete Gurson model and CZM with application to hydrogen embrittlement 

      Lin, Meichao; Yu, Haiyang; Ding, Yu; Olden, Vigdis; Alvaro, Antonio; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2022)
      A general simulation framework for modelling ductile-to-brittle transition in metals is proposed. The method combines the complete Gurson model and cohesive zone model, which brings ductile and brittle fracture mechanisms ...
