Weakly Interacting Massive Particle (WIMP) direct detection experiments are closing in on the region of parameter space where neutralinos may constitute the Galactic halo dark matter. Numerical simulations and observations of galaxy halos indicate that the standard Maxwellian halo model is likely to be a poor approximation to the dark matter distribution. We examine how halo models with triaxia...

The current status of the application of covariant density functional theory to microscopic description of nuclear fission with main emphasis on superheavy nuclei (SHN) is reviewed. The softness of SHN in the triaxial plane leads to an emergence of several competing fission pathes in the region of the inner fission barrier in some of these nuclei. The outer fission barriers of SHN are considera...

Hot deformation is one of the main technological stages products made from metallic materials. It strictly required to decrease costs developing optimized technologies at this stage without a significant in products’ quality. The present investigation offers an algorithm unite three different models predict hot behavior, fracture, and microstructure evolution. compression tension tests AISI 316...

We make the hypothesis that molecular cloud fragments are triaxial bodies with a large scale magnetic field oriented along the short axis. While consistent with theoretical expectations, this idea is supported by magnetic field strength data, which show strong evidence for flattening along the direction of the mean magnetic field. It is also consistent with early submillimeter polarization data...

Rotational behavior inducing triaxiality is discussed for Cr in the cranked NilssonStrutinsky (CNS) model, as well as in the spherical shell model. It is shown that the low-spin region up to about I=8, has a prolate well-deformed shape. At higher spins the shape is triaxial with a “negative-γ” deformation, that is, with rotation around the classically forbidden intermediate axis. By comparing c...

In this paper, the microstructural damage evolution of a steel with ferrite–pearlite microstructure (C45E) was investigated during process cold upsetting. The development and accumulation were analyzed in different areas samples that deformed at strain levels. scanning electron microscopy (SEM) results showed various mechanisms nucleation microcavities occurred upsetting process. quantitative t...

The mechanical response of isotropic elastoplastic materials containing random distributions initially spherical voids is investigated computationally based on Fast Fourier Transform simulations. Numerical limit-analysis simulations at constant stress triaxiality allow to determine the yield surfaces, leading in particular determination a Representative Volume Element size for onset coalescence...

A novel single shear specimen (SSS) together with a correction coefficient method is used to study the deformation behavior of 304 stainless steel under loadings. Shear stress-shear strain relations over wide range rates (0.001 39000 s?1) at three initial temperatures (77 473 K) are obtained experimentally. The effects rate and temperature on flow stress curves determined. With increasing or te...
