The Three-Dimensional Shapes of Galaxy Clusters

, 2012
While clusters of galaxies are considered one of the most important cosmological probes, the standard spherical modelling of the dark matter and the intracluster medium is only a rough approximation.

High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

Computational Investigation on the Combined Effect of Applied Strain and Pore Configuration on Strain Concentrators in Additively Manufactured Metals

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1656-1679, May 2026.
ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...

The Centers of Early-Type Galaxies with HST III: Non-Parametric Recovery of Stellar Luminosity Distributions

, 1996
We have non-parametrically determined the luminosity density profiles and their logarithmic slopes for 42 early-type galaxies observed with HST. Assuming that the isodensity contours are spheroidal, then the luminosity density is uniquely determined from

Lopsidedness of self-consistent galaxies by the external field effect of clusters

, 2017
Adopting Schwarzschild's orbit-superposition technique, we construct a series of self-consistent galaxy models, embedded in the external field of galaxy clusters in the framework of Milgrom's MOdified Newtonian Dynamics. These models represent relatively

Experimental study of the end effect on the mechanical behaviors of rocks under true 3D compressions

Energy Science & Engineering
In true triaxial compression tests, all three principal stresses are imposed independently. This allows for a more comprehensive analysis of the material's mechanical properties.

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 ...
