Yield conditions for deformation of amorphous polymer glasses

, 2001
Shear yielding of glassy polymers is usually described in terms of the pressure-dependent Tresca or von Mises yield criteria. We test these criteria against molecular dynamics simulations of deformation in amorphous polymer glasses under triaxial loading

Use of elastic stability analysis to explain the stress-dependent nature of soil strength [PDF]

, 2015
The peak and critical state strengths of sands are linearly related to the stress level, just as the frictional resistance to sliding along an interface is related to the normal force. The analogy with frictional sliding has led to the use of a ‘friction

Theoretical solution for the relationship between strength parameters of direct shear test and triaxial test

Yantu gongcheng xuebao
This paper analyzes the variation law of the Mohr's stress circle for normally consolidated soils in direct shear tests and triaxial compression tests. By comparing and analyzing the stress paths during the shearing process of the two tests, it is found ...

Stress-Dilatancy for Soils. Part II: Experimental Validation for Triaxial Tests

Studia Geotechnica et Mechanica, 2016
Different forms of the stress-dilatancy relations obtained based on the frictional theory for the triaxial condition are presented. The analysed test data show that the shear resistance of many soils is purely frictional.

Direct measurement of dark matter halo ellipticity from two-dimensional lensing shear maps of 25 massive clusters [PDF]

, 2010
We present new measurements of dark matter distributions in 25 X-ray luminous clusters by making a full use of the two-dimensional (2D) weak lensing signals obtained from high-quality Subaru/Suprime-Cam imaging data.

Morphologies of three-dimensional shear bands in granular media

, 2007
We present numerical results on spontaneous symmetry breaking strain localization in axisymmetric triaxial shear tests of granular materials. We simulated shear band formation using three-dimensional Distinct Element Method with spherical particles.

On-sample water content measurement for a complete local monitoring in triaxial testing of unsaturated soils [PDF]

, 2012
To provide a complete local monitoring of the state of an unsaturated soil sample during triaxial testing, a local water content measurement device was adapted to a triaxial device comprising the measurement of local displacements (Hall effect ...

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.

Temperature effect of rockburst in granite caverns: insights from reduced-scale model true-triaxial test

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
To investigate the influence of thermal treatment on the rockburst in granite caverns, true-triaxial compression tests were conducted on pre-heated granite cubic samples containing a circular through-hole using a true-triaxial test system, and the micro ...
