A framework for predicting the local stress-strain behaviors of additively manufactured multiphase alloys in the sequential layers
Liu, Siqi; Lin, Meichao; Wang, Xu; Fu, Yuequn; Ren, Xiaobo; Zhang, Zhiliang; He, Jianying (Peer reviewed; Journal article, 2022)The additive manufacturing (AM) process often results in non-uniform microstructure and different mechanical properties in sequential layers, impacting the overall performance of the AM-ed component. However, it is extremely ... -

Investigation of hydrogen embrittlement behavior in X65 pipeline steel under different hydrogen charging conditions
Wang, Dong; Hagen, Anette Brocks; Undrum Fathi, Pernille; Lin, Meichao; Johnsen, Roy; Lu, Xu (Peer reviewed; Journal article, 2022)The hydrogen effect on a X65 carbon steel was investigated by tensile tests under both ex-situ and in-situ hydrogen charging conditions. The fractured samples were characterized and compared using a combination of scanning ... -
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 ... -
Nanoscale creep behavior and its size dependency of a Zr-based bulk metallic glass manufactured by selective laser melting
Liu, Siqi; Chang, Zexin; Fu, Yuequn; liu, yuyu; Lin, Meichao; Ren, Xiaobo; Wang, Wenxian; Zhang, Zhiliang; He, Jianying (Peer reviewed; Journal article, 2022)Nanoscale creep behaviors of metallic glasses (MGs) have gathered considerable interests in recent years, owing to their distinct atomistic mechanisms of plasticity. Additive manufacturing (AM) is a burgeoning technique ... -
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 ...
