strain-rate hardening and thermalsoftening exists throughout the process.It is found that shear band develops at a 4 5-degree angle to thecompression axis.In the light of given patterns of deformation and temperature,shear band evolutionaccelerated by thermal softening is retarded by the inertial ...
A GPU-based two-dimensional discrete element methodology allowing for grain rolling resistance is adopted to study the engineering and fundamental aspects of shear band formation in normal and reverse faulting through an initially dense sand; of course, the paper emphasizes on fundamental aspects. The...
S.R. Elliott, in Encyclopedia of Condensed Matter Physics (Second Edition), 2024 Introduction In this article, the term “electronic structure” is taken to mean a description of the details of the solution, in its totality, of the Schrödinger equation for electrons in solids. Two quantities...
In Fig.3a,b, the band dispersions show generally decreasing dependence (seen from the magnitude of coefficients) on basis terms with increasing complexities (Fig.3a), and the majority of dispersion is encoded into a subset of the terms (Fig.3b). This observation implies that moderate smoothing ...
We conducted a large-scale density-functional theory study on the influence of the exchange-correlation functional in the calculation of electronic band gaps of solids. First, we use the large materials data set that we have recently proposed to benchmark 21 different functionals, with a particular...
Formation.The main factors involved in soil formation are climate, parent material, plants and animals, topography, the geological age of the land, and man’s economic activity. Climate influences the weathering of rock, affects the soil’s thermal and water regimes, thereby regulating the processe...
Measurement of the temperature profile during shear band formation in steels deforming at high strain rates A torsional Kolsky bar (split-Hopkinson bar) was used to deform tubular specimens of AISI 1018 cold rolled steel and AISI 1020 hot rolled steel at a nomina... KAHDH Hawley - 《Journal ...
We investigated the effect of built-in electric field on miniband formation and carrier nonradiative recombination in a superlattice structure by using pho... T Nakamura,K Matsuochi,H Suzuki - Advanced Materials & Characterization Techniques for Solar Cells 被引量: 0发表: 2017年 Modelling of GaAs...
We numerically study the formation of a hierarchy of minibands and gaps as N increases using a Kronig–Penney model. Increasing n empirically results in a more fragmented miniband and gap structure due to the rapid increase in the number of minibands and gaps as n increases, in agreement ...
in the structure of CeO2is widely studied. Andersson et al. [10] used ab-initio calculations to calculate the redox thermodynamics and kinetics of CeO2mixed with ZrO2. It was found that Zr4+doping decreased the vacancy formation energy and the migration barrier in CeO2[10]. Yang [6] and...
