    • 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 new method to estimate the residual stresses in additive manufacturing characterized by point heat source 

      Sun, Li; Ren, Xiaobo; He, Jianying; Olsen, Jim Stian; Pallaspuro, Sakari; Zhang, Zhiliang (Peer reviewed; Journal article, 2019)
      Residual stress in additive manufacturing (AM) is one of the key challenges in terms of structural integrity and finish quality of printed components. Estimating the residual stress distribution on additively manufactured ...
