Strain Rate-Dependent Constitutive and Low Stress Triaxiality Fracture Behavior Investigation of 6005 Al Alloy

Advances in Materials Science and Engineering, 2018
In order to study the dynamic and fracture behavior of 6005 aluminum alloy at different strain rates and stress states, various tests (tensile tests at different strain rates and tensile shearing tests at five stress states) are conducted by Mechanical ...

Fracture Initiation in Aluminum Alloys Under Multiaxial Loading at Various Low Strain Rates

Metals
The initiation of ductile fractures in medium-strength AW5754 and high-strength AW6082 aluminum alloys at different quasi-static strain rates and under multiaxial stress states was investigated through a series of tensile tests using various specimen ...

An MCMC Fitting Method for Triaxial Dark Matter Haloes [PDF]

, 2008
Measuring the 3D distribution of mass on galaxy cluster scales is a crucial test of the LCDM model, providing constraints on the behaviour of dark matter. Recent work investigating mass distributions of individual galaxy clusters (e.g.

Projection effects in cluster mass estimates : the case of MS2137

, 2005
We revisit the mass properties of the lensing cluster of galaxies MS2137-23 and assess the mutual agreement between cluster mass estimates based on lensing, X-rays and stellar dynamics.

Large scale anisotropies on halo infall [PDF]

, 2010
We perform a statistical analysis of the peculiar velocity field around dark matter haloes in numerical simulations. We examine different properties of the infall of material onto haloes and its relation to central halo shapes and the shape of the large ...

Influence of Failure Strain of Different Aluminium Alloys on Dynamic Problems

Engineering Transactions, 2014
In this work an experimental-numerical methodology is devised for analyzing ductile fracture of two aluminum alloys under different values of stress triaxiality (0.2 ≤ η ≤ 1.2) and Lode parameter (−1 ≤ μ ≤ 0).

Ductile fracture simulations using a multi-surface coupled damage-plasticity model [PDF]

, 2017
In this paper, an isotropic porous metal plasticity model accounting for both void growth by diffuse plastic deformation and void ‘coalescence’ by localization of plastic flow in the inter-void ligaments is presented.

Spontaneous fission modes and lifetimes of super-heavy elements in the nuclear density functional theory

, 2012
Lifetimes of super-heavy (SH) nuclei are primarily governed by alpha decay and spontaneous fission (SF). Here we study the competing decay modes of even-even SH isotopes with 108
