Ductile damage and fracture prediction in real size structures subjected to complex loading
conditions has been of utmost interest in the scientific and engineering community in the …

A ductile fracture criterion is newly proposed to model fracture behavior of sheet metals for
nucleation, growth and shear coalescence of voids during plastic deformation. In the new …

This paper introduces a set of coupled viscoplastic constitutive equations for deformation
and damage in hot stamping and cold die quenching of AA6082 panel parts. The equation …

The formability of the material determines the amount of available deformation before failure
and thus is important for the production of various structural components in industries. The …

This paper deals with ductile fracture behaviors of a typical BCC metal with the variation of
the strain rate. Ductile fracture behaviors of AISI 4130 steel for BCC metals are investigated …

Out-of-plane (dome) formability test is used extensively to determine forming limit diagrams
(FLDs) of sheet metals. Strain paths are generated to form the FLD using this test. In this …

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 …

In order to analyze and control surface crack during tube spinning of titanium alloy, six
ductile fracture criteria (DFCs) were incorporated into the finite element software (ABAQUS) …

The present research aimed to investigate the ductile fracture during the forming of 5083-O
aluminum alloy sheet and establish a rational criterion to predict it. Seven specimens with …

In this paper, we propose an extended ductile fracture criterion to study forming limit of DP
590 steel sheet. This criterion involves two independent parameters, stress triaxiality η and …
