It is still a challenge to numerically achieve the interactive competition between ductile damage and brittle fracture in ductile-to-brittle transition (DBT) region. In addition, since two types of fracture occur at two independent material length scales, it is difficult to process them with the sam...

Recently, the authors in this paper proposed a correction function to determine material’s equivalent stress-strain curve with axisymmetric-notched tensile specimens. In this study, tensile tests were performed at room temperature, -30℃ and -60℃ with axisymmetric notched tensile specimens to verify ...

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 materials exhibiting the Lüders plateau, it has been reported that lower...

The brittle-to-ductile transition (BDT), no matter what the dominated mechanism is, dislocation nucleation or dislocation motion, is not an intrinsic phenomenon of material, and depends not only on the strain rate but also on the constraint at crack tip. However, few work has been performed on study...
