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 ...

Experimental study on impact dynamics and failure characteristics of coal specimen under true triaxial conditions

Meitan xuebao, 2023
Deep coal is mostly in a three-dimensional unequal stress state. In order to study the dynamic characteristics of coal under impact load, the dynamic failure mechanics experiment of coal was carried out by true triaxial Hopkinson experimental system ...

Estimating Black Hole Masses in Triaxial Galaxies [PDF]

, 2009
Most of the super massive black hole mass estimates based on stellar kinematics use the assumption that galaxies are axisymmetric oblate spheroids or spherical.

Modeling the gravitational potential of a cosmological dark matter halo with stellar streams [PDF]

, 2016
Stellar streams result from the tidal disruption of satellites and star clusters as they orbit a host galaxy, and can be very sensitive probes of the gravitational potential of the host system. We select and study narrow stellar streams formed in a Milky-

Structural properties of disk galaxies. II. Intrinsic shape of bulges [PDF]

, 2010
(Abridged) The structural parameters of a magnitude-limited sample of 148 unbarred S0-Sb galaxies were analyzed to derive the intrinsic shape of their bulges.

Weak lensing by triaxial galaxy clusters [PDF]

, 2011
Weak gravitational lensing studies of galaxy clusters often assume a spherical cluster model to simplify the analysis, but some recent studies have suggested this simplifying assumption may result in large biases in estimated cluster masses and ...

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
