We present the first physical model for the non-spherical intra-cluster gas distribution in hydrostatic equilibrium under the gravity of triaxial dark matter halos. Adopting the concentric triaxial density profiles of the dark halos with constant axis ratios proposed by Jing & Suto (2002), we derive an analytical expression for the triaxial halo potential on the basis of the perturbation theory...

Hubble Space Telescope (HST) observations reveal that the density of stars in most elliptical galaxies rises toward the center in a power-law cusp. Many of these galaxies also contain central dark objects, possibly supermassive black holes. The gravitational force from a steep cusp or black hole will destroy most of the box orbits that constitute the " backbone " of a triaxial stellar system. D...

Cyclic loading affects the long-term response of geostructures build on natural soils. Soft soils are particularly susceptible to development large deformations, induced by repetitive nature loading. A new viscoplastic cyclic accumulation model is presented, which an hierarchical extension Creep-SClay1S model, permanent deformation resulting from undrained soft clays. The cumulative strains inc...

SUMMARY Crustal rocks undergo repeated cycles of stress over time. In complex tectonic environments where stresses may evolve both spatially and temporally, such as volcanoes or active fault zones, these experience not only cyclic loading unloading, but also rotation and/or reorientation stresses. situations, any resulting crack distributions form sequentially therefore be highly anisotropic. T...

Recent work on the dynamics of triaxial stellar systems is reviewed. The motion of boxlike orbits in realistic triaxial potentials is generically stochastic. The degree to which the stochasticity manifests itself in the dynamics depends on the chaotic mixing timescale, which is a small multiple of the crossing time in triaxial models with steep cusps or massive central singularities. Low-lumino...

The effect of crack angle on energy evolution during sandstone failure subjected to true triaxial cyclic loading and unloading is great concern. However, the consumed in initiation compaction process generally referred dissipated energy, which inaccurate. To reveal law breaking sandstone, a complex test carried out precast angled samples by employing system. area integral methodology exploited ...

We have constructed realistic, self-consistent models of triaxial elliptical galaxies embedded in triaxial dark matter haloes. We examined three different models for the shape of the dark matter halo: (i) the same axis ratios as the luminous matter (0.7:0.86:1); (ii) a more prolate shape (0.5:0.66:1); (iii) a more oblate shape (0.7:0.93:1). The models were obtained by means of the standard orbi...
