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 (Journal article; Peer reviewed, 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 ... -
Unraveling Ice–Solid Interface Rupture Dynamics: Insights from Molecular Dynamics Simulations
Chang, Yuanhao; Xiao, Senbo; Yu, Haiyang; Ma, Rui; Skallerud, Bjørn Helge; Zhang, Zhiliang; He, Jianying (Peer reviewed; Journal article, 2024)Unwanted icing on exposed surfaces poses significant risks, driving the quest for effective anti-icing mechanisms. While fracture mechanics concepts have been developed for designing coatings that weaken the ice–solid ... -
Viscous regularization for cohesive zone modelling under constant displacement: an application to hydrogen embrittlement simulation
Yu, Haiyang; Olsen, Jim Stian; Olden, Vigdis; Alvaro, Antonio; He, Jianying; Zhang, Zhiliang (Journal article; Peer reviewed, 2016)The convergence problem during the cohesive zone modelling of hydrogen embrittlement in constant displacement scenario is attributed to the numerical instability which is studied analytically in the present work. The ...
