Trends in the cohesive properties of sp bonded elements
نویسندگان
چکیده
2014 The trends in the cohesive energy, nearest-neighbour distance and compressibility of all sp bonded elements are discussed using a semiempirical tight binding approach. It is first shown that two very simple models describe these trends and also demonstrate the Grimm-Sommerfeld rule for elements with more than a half filled valence shell. A more complete numerical calculation is then performed which confirms these predictions, giving results in quantitative agreement with the observed values. J.

Cohesion energetics of carbon allotropes: quantum Monte Carlo study.
We have performed quantum Monte Carlo calculations to study the cohesion energetics of carbon allotropes, including sp(3)-bonded diamond, sp(2)-bonded graphene, sp-sp(2) hybridized graphynes, and sp-bonded carbyne. The computed cohesive energies of diamond and graphene are found to be in excellent agreement with the corresponding values determined experimentally for diamond and graphite, respec...
متن کاملEffects of Degree of Consolidation and Anisotropic Consolidation Stresses on Shear Modulus and Damping Ratio of Cohesive Soils at Low Strain
During consolidation process of saturated cohesive soil the soil stiffness increases. Increase of the effective stress due to dissipation of excess pore pressure causes additional stiffness of soil mass. This phenomenon has a very important effect on the behavior of saturated cohesive soils during dynamic loading. In the current investigation the changes in maximum shear modulus. Gmax and dampi...

Background and Aims: The aim of this study was to evaluate the effect of application of two types of primers over bracket bases on the shear bond strength (SBS) and mode of bond failure.Materials and Methods: In this study, 75 human premolar teeth were divided into three equal groups. In group 1 (control), after surface preparation of enamel by conventional method (acid etching+primer) brackets...
متن کاملSubstitution as a Device of Grammatical Cohesion in English Contexts
The present study set out to investigate the effect of teaching substitution as a kind of grammatical cohesion on the true identification of confusing substitution elements with cohesive or non-cohesive roles in different contexts and also the production of modal, reporting and conditional contexts through clausal substitution acquaintance. To this end, the following procedures were taken. Firs...
متن کاملFinite element analysis (FEA) modeling on adhesive joint for composite fuselage model
In this paper, a finite element modeling via ABAQUS/Explicit simulation on a novel fabrication miniature composite fuselage structure is presented. The fuselage structure is modeled as a continuum composite layup that consisted of a woven C-glass fiber/epoxy 200 g/m 2 composite laminated [908] with the orthotropic elastic material properties and adhesively bonded butt joint. The adhesively bond...
