Stress triaxiality and failure in SFRPs: a novel workflow for failure curve determination, considering fibre orientation and specimen geometry

open access: yesPolymer Testing
This research investigates the static failure behaviour of a PA6T/6I GF50, focusing on the distribution of the stress triaxiality at critical points where failure is expected.

A Degradation Function Consistent with Cocks–Ashby Porosity Kinetics [PDF]

open access: yes, 2018
The load carrying capacity of ductile materials degrades as a function of porosity, stress state and strain-rate. The effect of these variables on porosity kinetics is captured by the Cocks–Ashby model; however, the Cocks–Ashby model does not account for

Experimental study of the high strain rate shear behaviour of Ti6Al4V [PDF]

open access: yes, 2011
Three different high strain rate shear test techniques are applied on the titanium alloy Ti6Al4V. Two techniques for testing of bulk materials and one technique for sheet materials are used: torsion of thin-walled tubes, compression of hat-shaped ...

A Fracture Criterion for Prediction of Fracture Initiation of Metal Materials at Various Stress States for Nuclear Waste Storage

open access: yesScience and Technology of Nuclear Installations, 2019
A fracture criterion is newly proposed to evaluate fracture behavior and predict fracture initiation of metal materials in different complicated stress states for four different fracture mechanisms including quasicleavage fracture, normal fracture with ...

Triaxial vs. Spherical Dark Matter Halo Profiles

open access: yes, 2006
When analysing dark matter halos forming in cosmological N-body simulations it is common practice to obtain the density profile utilizing spherical shells. However, it is also known that the systems under investigation are far from spherical symmetry and

The Spin-Orbit Evolution of GJ 667C System: The Effect of Composition and Other Planet's Perturbations [PDF]

open access: yes, 2016
Potentially habitable planets within the habitable zone of M-dwarfs are affected by tidal interaction. We studied the tidal evolution in GJ 667C using a numerical code we call TIDEV.

Comparison of gurson and lemaitre model in the context of blanking simulation of a high strength steel [PDF]

open access: yes, 2017
The process of blanking takes place in a short band with high accumulated strain undergoing various stress triaxialities. Enhanced implementations for shear and compressive loads of Gurson’s and Lemaitre’s model are directly compared for the same ...

STUDY ON NECKING AND FRACTURE OF DUCTILE MATERIALS BASED ON STRESS TRIAXIALITY

open access: yesJixie qiangdu, 2015
Stress triaxiality is a key factor in controlling the fracture of materials. Based on new method of finite element aided testing( FAT),the full-range constitutive relationship of ductile materials could be obtained. Thus,the distribution and evolution of
