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 (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 ... -
Residual stresses and dimensional deviation in metal additive manufacturing: prediction and mitigation methods
Sun, Li (Doctoral theses at NTNU;2020:411, Doctoral thesis, 2020)Additive manufacturing (AM) has attracted wide attention over the past years due to its various advantages, such as design freedom, less production cost, and short production cycles. However, residual stresses and dimensional ... -
Stress-strain curves of metallic materials and post-necking strain hardening characterization: A Review
Tu, Shengwen; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Journal article; Peer reviewed, 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 (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 ...
