A finite-strain hyperviscoplastic model and undrained triaxial tests of peat

open access: yes, 2017
This paper presents a finite-strain hyperviscoplastic constitutive model within a thermodynamically consistent framework for peat which was categorised as a material with both rate-dependent and thermodynamic equilibrium hysteresis based on the data ...

Evidence for Dark Matter Annihilation from Galactic Gamma Rays?

open access: yes, 2004
The diffuse galactic EGRET gamma ray data show a clear excess for energies above 1 GeV in comparison with the expectations from conventional galactic models. The excess is seen with the same spectrum in all sky directions, as expected for Dark Matter (DM)

One-dimensional compression of a crushable sand in dry and wet conditions [PDF]

open access: yes, 2015
This paper presents the results of a series of dry and wet one-dimenional compression tests on a calcareous sand from the Persian Gulf. Calcareous grains crush more easily compared to silica grains, a fact that is mainly attributed to their angular shape

Star cluster evolution in barred disc galaxies. I. Planar periodic orbits

open access: yes, 2011
The dynamical evolution of stellar clusters is driven to a large extent by their environment. Several studies so far have considered the effect of tidal fields and their variations, such as, e.g., from giant molecular clouds, galactic discs, or spiral ...

PRENOLIN project. Results of the validation phase at sendai site [PDF]

open access: yes, 2017
One of the objectives of the PRENOLIN project is the assessment of uncertainties associated with non-linear simulation of 1D site effects. An international benchmark is underway to test several numerical codes, including various non-linear soil ...

Effect of Fissure Penetration Degrees on Spalling Process and Feature of Surrounding Rock in Rectangular Tunnel Under True Triaxial Loading

open access: yesApplied Sciences
To investigate the effect of fissure penetration on the spalling process and features of rectangular tunnel sidewalls, true triaxial compression tests were conducted on cubic sandstone specimens with varying fissure penetration degrees. Acoustic emission

The Peaks Formalism and the Formation of Cold Dark Matter Haloes

open access: yes, 2011
We use two cosmological simulations of structure formation to study the conditions under which dark matter haloes emerge from the linear density field.

Thermo-mechanical analysis of wellbore stability in ultra-deep formations

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
Wellbore stability is crucial for ultra-deep wells operating under high temperature and high stress conditions. To analyze the effects of thermal shock and horizontal stress on wellbore stability, a series of true triaxial compression experiments and ...
