Adiabatic heating of PolyAmide 11 under monotonic loading : effects of the initial stress triaxiality ratio

open access: yes, 2021
International audienceAssociated with the partial conversion of plastic work into dissipative heat [1], adiabatic heat build-up of polymers under mechanical loading may be exceptionally high so that it can locally reach the glass transition temperature ...

New void growth-based ductile fracture models incorporating interaction effects of stress triaxiality and Lode angle parameter

open access: yes
The void growth rate in ductile fracture is influenced by both the stress triaxiality and Lode angle parameter. Traditional ductile fracture models often treat these effects independently, combining them as the product of two isolated terms.

Analysis of the influence of stress triaxiality on formability of hole-flanging by single-stage SPIF

open access: yes, 2019
Traditionally the fracture in sheet metal forming is characterized by the fracture forming limit (FFL) curve typically obtained by using conventional Nakajima tests. This curve is implicitly assumed a material property.

Evaluation of ductile fracture criteria in a general three-dimensional stress state considering the stress triaxiality and the lode parameter

open access: yes, 2013
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 strain to fracture.

On the Determination of Stress Triaxiality in a Cast Aluminum Alloy

open access: yes
This study presents a prediction of fracture behavior in the cast material AlSi10MnMg-T7 under multiaxial loading conditions. The main goal is to establish a triaxiality locus, which is a diagram illustrating the relationship between the equivalent ...

Stress Modified Critical Strain criterion for S235JR steel at low initial stress triaxiality

open access: yes, 2014
Ductile fracture of low carbon structural steel (S235JR) at low initial stress triaxiality has been predicted using a method based on the Stress Modified Critical Strain (SMCS) crite- rion and the Gurson-Tvergaard-Needleman (GTN) material model.
