Ductile fracture by void growth to coalescence

AA Benzerga, JB Leblond - Advances in applied mechanics, 2010 - Elsevier

[HTML][HTML] Rupture mechanisms in combined tension and shear—Micromechanics

I Barsoum, J Faleskog - International journal of solids and structures, 2007 - Elsevier
A micromechanics model based on the theoretical framework of plastic localization into a
band introduced by Rice is developed. The model consists of a planar band with a square …

On stress-state dependent plasticity modeling: Significance of the hydrostatic stress, the third invariant of stress deviator and the non-associated flow rule

X Gao, T Zhang, J Zhou, SM Graham, M Hayden… - International Journal of …, 2011 - Elsevier
It has been shown that the plastic response of many materials, including some metallic
alloys, depends on the stress state. In this paper, we describe a plasticity model for isotropic …

Effects of the stress state on plasticity and ductile failure of an aluminum 5083 alloy

X Gao, T Zhang, M Hayden, C Roe - International Journal of Plasticity, 2009 - Elsevier
The experimental and numerical work presented in this paper reveals that stress state has
strong effects on both the plastic response and the ductile fracture behavior of an aluminum …

[HTML][HTML] Modeling of ductile fracture: significance of void coalescence

X Gao, J Kim - International journal of solids and structures, 2006 - Elsevier
In this paper void coalescence is regarded as the result of localization of plastic flow
between enlarged voids. We obtain the failure criterion for a representative material volume …

An assessment of isotropic constitutive models for ductile fracture under high and low stress triaxiality

L Malcher, FMA Pires, JMAC De Sá - International Journal of Plasticity, 2012 - Elsevier
In this contribution, a numerical assessment of three isotropic constitutive models is
performed in order to identify their applicability and reliability in the prediction of ductile …
