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 ... -
Numerical investigation of a novel pattern for reducing residual stress in additive manufacturing
Sun, Li; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2020)Deposition patterns can significantly affect residual stress distribution in additive manufacturing processes. In this paper, a novel deposition pattern, the S-pattern, is proposed for the additive manufacturing process. ... -
Numerical study on the effect of the Lüders plateau on the ductile crack growth resistance of SENT specimens
Tu, Shengwen; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2018)The increasing demand of energy prompts the petroleum industry exploitation activities to the Arctic region where the low temperature is a strong challenge, both for structural design and material selection. For structural ... -
Passive Snow Repulsion: A State-of-the-art Review Illuminating Research Gaps and Possibilities
Andersson, Per-Olof; Jelle, Bjørn Petter; Zhang, Zhiliang (Journal article; Peer reviewed, 2017)Building integrated photovoltaics (BIPV) are becoming more common every day. They are used everywhere, from the cabin in the mountains to the modern apartment building, and with more common use, strengths and weaknesses ... -
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 ... -
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 ...
