In this study, the ductile fracture of the alloy metal is analyzed. First, the key factors affecting
the initiation of ductile fracture are investigated. Then, a new uncoupled ductile fracture …

An anisotropic ductile fracture criterion is proposed for ductile fracture of lightweight metals.
The ductile fracture criterion couples effect of stress triaxiality on void growth, and assumes …

This paper is concerned with the extension of a shear-controlled ductile fracture criterion for
accurate prediction of fracture forming limit diagrams (FFLD) in sheet metal forming …

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 …

A macroscopic ductile fracture criterion is proposed based on micro-mechanism analysis of
nucleation, growth and shear coalescence of voids from experimental observation of fracture …

This paper is concerned with evaluation of various ductile fracture criteria in a general three-
dimensional stress state of stress triaxiality, the Lode parameter and the equivalent plastic …

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 …

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 …

A new ductile fracture criterion (DFC) is developed based on two typical fracture
mechanisms-tension fracture and shear fracture by analyzing the morphologies of the …

The present paper deals with a modification of the stress triaxiality-based Lemaitre damage
model to predict the ductile fracture at low stress triaxiality and shear-dominated loadings …
