Based on continuum damage mechanics and stress invariants, a novel multi-parameters
ductile fracture model is proposed by coupling the synergistic effects of hydrostatic pressure …

A modified ductile fracture model is proposed based on continuum damage mechanics and
three-stress-invariant criteria. In the modified model, the effects of hydrostatic pressure and …

In this study, the ductile fracture of the alloy metal is analyzed. First, the key factors affecting
the initiation of ductile fracture are investigated. Then, a new uncoupled ductile fracture …

Data-driven methods based on machine learning (ML) models offer new approaches for
characterizing the fracture behavior of advanced elastoplastic materials. In this paper, a ML …

This paper is a contribution to the ductile fracture prediction by the proposal of a new
uncoupled ductile fracture criterion. In the new criterion, two typical void deformation models …

A ductile fracture model is proposed to describe shear fracture of sheet metals from shear to
balanced biaxial tension via uniaxial and plane strain tension. The fracture criterion models …

Based on experiments and computational modeling, this study examines the failure
behavior of structural steel, HY-100, which has been pre-strained at a high stress triaxiality …

This study introduces a modified DF2016 criterion to model a ductile fracture of sheet metals
from shear to equibiaxial tension. The DF2016 criterion is modified so that a material …

In the thermoforming process of complex components, such as the multi-directional loading
forming of multi-cavity parts, complex stress states always exist and change. Meanwhile …
