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 …

The stress state is one of the most notable factors that dominates the initiation of ductile
fracture. To examine the effects of the stress state on plasticity and ductile failure, a new …

Guided by previous theoretical analyses, an experimental program was designed to probe
the path-dependence of the fracture locus in ductile materials. The material and loading …

The fracture initiation in ductile materials is governed by the damaging process along the
plastic loading path. A new damage plasticity model for ductile fracture is proposed …

A damage plasticity model for ductile fracture is proposed. This model is established on the
cylindrical coordinate system of principal stress space. Experimental results show that …

Numerous criteria have been developed for ductile fracture (DF) prediction in metal plastic
deformation. Finding a way to select these DF criteria (DFCs) and identify their applicability …

Recent research studies on ductile fracture of metals have shown that the ductile fracture
initiation is significantly affected by the stress state. In this study, the effects of the stress …

The effective plastic strain is a commonly used damage variable within continuum damage
framework. The value of effective plastic strain at fracture, however, depends on strain rate …

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 …

The continuum mechanical simulation of the microstructural damage process is important in
the study of ductile fracture mechanics. In this paper, the continuum damage mechanics …
