This research was aimed to predict the ductile fracture for aluminum alloy 5083-O sheet
using a phenomenological Modified Mohr-Coulomb fracture (MMC) criterion. The plasticity …

In this paper, the modified Mohr-Coulomb (MMC) ductile fracture criterion was adopted to
analyze the fracture behavior of the AA6061-T6 aluminum alloy sheet during the U-bending …

This paper is concerned with accurate prediction on the fracture strain and fracture forming
limit curve (FFLC) by calibrating the material constants by the specimens with reasonable …

Based Lou-2013 ductile fracture criterion, the ductile fracture and mechanical property of
5182 aluminum alloy is studied and the tension tests of hole specimen, plain strain …

The application of ductile fracture criteria (DFCs) in numerical analysis of sheet metal
forming processes can lead to the accurate determination of the fracture initiation. In this …

A modified ductile fracture criterion is proposed based on the traditional Ayada criterion and
coded into the finite element simulation platform of VUMAT/ABAQUS for prediction and …

Abstract The Gurson-Tvergaard-Needleman model (GTN model) was employed to predict
the ductile fracture behaviour in the forming of aluminium alloy 5A06 sheet. The in-situ …

In this paper, the effects of strain path change on the forming limit diagram (FLD) of AA5083
sheet were investigated. The aim is to predict the forming limit curve (FLC) with non …

The ductile fracture behavior of anisotropic materials was modeled by the uncoupled ductile
fracture criterion. The ductile fracture model was concerned with the micro mechanisms of …

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 …
