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 ... -
Stress-strain curves of metallic materials and post-necking strain hardening characterization: A Review
Tu, Shengwen; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2019)For metallic materials, standard uniaxial tensile tests with round bar specimens or flat specimens only provide accurate equivalent stress–strain curve before diffuse necking. However, for numerical modelling of problems ... -
Study of low-temperature effect on the fracture locus of a 420-MPa structural steel with the edge tracing method
Tu, Shengwen; Ren, Xiaobo; Kristensen, Tore Andre; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2018)Quasi-static tensile tests with smooth round bar and axisymmetric notched tensile specimens have been performed to study the low-temperature effect on the fracture locus of a 420-MPa structural steel. Combined with a digital ...
