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 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 …

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 …

Prediction of ductile failure onset in fracture-free materials has instigated several research
works in the last few years. The literature shows basically two general approaches:(i) post …

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 …

Simulation of fracture in ductile materials is a challenging problem, since it typically occurs at
length scales that are orders of magnitude smaller than that of the structures in which the …

Ductile damage appears in metallic materials when they undergo sufficiently high plastic
strain. It is caused by voids and produces degradation on the mechanical properties that …

Under dynamic loading conditions, the rapid nature of the fracture process may
simultaneously activate a considerable number of nucleation sites for void formation at the …

The paper discusses newexperiments to study the effect of non-proportional loading paths
on damage and fracture behavior of ductile metals. Specimens are taken from thin metal …

The ductile fracture in monotonic loading applies after extensive straining and may arise
after various complex loading paths. The role of loading path has been studied by …
