In this study, the plastic deformation behavior at a large strain range, as well as the ductile
damage and fracture of aluminum alloy 2024-O materials, were investigated under quasi …

In this work, the plasticity and ductile fracture behaviors of an aluminum alloy 5083-H116 are
studied through a series of experiments and finite element analyses. A recently developed …

The experimental and numerical work presented in this paper reveals that stress state has
strong effects on both the plastic response and the ductile fracture behavior of an aluminum …

To solve the problem that the original GTN model cannot accurately simulate ductile fracture
of material under low stress triaxiality, many scholars have made shear improvement to it …

Abstract The Gurson–Tvergaard–Needleman (GTN) model has provided a powerful
description of the nucleation growth and coalescence of micro voids, but it has limitations in …

The key point in this paper is the prediction of the onset of ductile fracture with a newly
proposed ductile fracture criterion in various stress state ranging from shear to uniaxial …

This paper investigates the influence of stress state on the equivalent plastic fracture strain
in 2024-T351 aluminum alloy. Eighteen unique stress states at failure—with triaxialities …

In this study, plasticity and ductile fracture properties were characterized by performing
various tension, shear, and compression tests. A series of 10 experiments were performed …

To numerically predict crack formation and growth of cast components under accidental
loading, it is necessary to characterize fracture properties at the macroscopic level. In this …

Abstract Aluminum alloy 6061-T6 (AA 6061-T6) extrusions have been widely applied in
large-span reticulated shells. However, researches on behaviors of the aluminum alloy …
