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 …

The aim of this paper is to gain insight for the transition of fracture initiation sites in notched
tensile specimens. For this purpose, a stress triaxiality-dependent viscoplastic damage …

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 …

To improve the accuracy of impact failure prediction of ductile material under complex stress
states, a novel multi-parameters dynamic ductile fracture model with constitutive relation and …

To predict fracture initiation in ductile material under nonproportional loadings, an approach
considering combined hardening and a fatigue-rule-based damage accumulation law was …

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 …

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 …
