The effect of residual stress on fracture of materials or structures has been widely studied. However, its influence on ductile-to-brittle transition (DBT), a crucial phenomenon of structural materials, has rarely been investigated so far. In the present study, employing the eigenstrain method resid...

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. The finite element method is used to study the temperature and stress field of ...

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 ...
