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 ...
