In this study, a new micromechanically-motivated phenomenological uncoupled fracture
model is proposed for predicting the ductile fracture of structural metals considering the …

A correct representation of the fracture limit for material subject to various stress states is
essential for the accurate prediction of fracture behavior. In this paper, a comprehensive …

In order to accurately describe the fracture behaviour of ductile metals in a wide range of
stress states, based on the mechanism of void nucleation, growth, and coalescence during …

The microvoid based Gurson-Tvergaard-Needleman (GTN) model is a powerful tool for
predicting ductile fracture behavior, and application of such model to steels and welds …

This paper provides a critical review of the commonly used computational fracture models in
structural engineering applications including:(a) Rice and Tracey void growth model;(b) …

A new ductile fracture criterion motivated by dislocation theory and void evolution is
proposed to predict fracture initiation of high-strength steels, which also considers size …

Shear stress ratio have recently been recognized as an important parameter, in addition to
stress triaxiality, that influences the initiation of ductile fracture in metals. In this paper, the …

Coarser grains lead to fewer voids on the fracture surfaces of miniaturized workpiece via
affecting the void nucleation, while finer grains result in a higher flow strength by influencing …

An isotropic ductile fracture criterion considering nucleation, growth, shear coalescence and
necking coalescence of voids during plastic deformation is developed to model fracture …

This paper presents a new micromechanics based ductile fracture initiation criterion for
ASTM A992 steels. The proposed criterion is developed using micromechanical study of …
