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 …

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 …

In the absence of geometrical constraints, ductile fracture has been identified as the
predominant mode of failure for structural elements under extreme loads, the prediction of …

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 present paper proposes ductile failure criteria in terms of true fracture strain (the
equivalent strain to fracture) as a function of the stress triaxiality (defined by the ratio of the …

Fracture in steel structures represents a critical limit state in evaluating the safety and
resiliency of civil infrastructure during earthquakes. This importance was demonstrated by …
