چکیده
We study the effect of mergers in the force chain model describing the stress profile in static granular materials. Combining numerical and analytical calculations, we show that granular materials do not generally behave in an elasticlike manner; however, they may under specific conditions, which are elaborated. Nonelastic behavior resulting from the nonlinearity of the full force chain model is discussed.

Lattice numerical simulations of hydraulic fractures interacting with oblique natural interfaces
The hydraulic fracturing propagation is strongly influenced by the existence of natural fractures. This is a very important factor in hydraulic fracturing operations in unconventional reservoirs. Various studies have been done to consider the effect of different parameters such as stress anisotropy, toughness, angle of approach and fluid properties on interaction mechanisms including crossing, ...
متن کاملElectromechanical Performance of NEMS Actuator Fabricated from Nanowire under quantum vacuum fluctuations using GDQ and MVIM
The Casimir attraction can significantly interfere the physical response of nanoactuators. The intensity of the Casimir force depends on the geometries of interacting bodies. The present paper is dedicated to model the influence of the Casimir attraction on the electrostatic stability of nanoactuators made of cylindrical conductive nanowire/nanotube. An asymptotic solution, based on path-integr...
متن کاملComparing the elastomeric behavior and force degradation pattern between different orthodontic elastomeric chains
Background and Aims: Elastomeric chains are known as a current device with the purpose of dental movement in orthodontic treatments. The aim of this study was to compare the elastomeric behavior and force degradation rate between different elastomeric chains existing in Iran in different time durations. Materials and Methods: 11 different elastomeric chains used in this study were: Class One, ...
متن کاملLocal Equilibrium for a One Dimensional Zero Range Process
Collective phenomena are present in several models of interacting particle systems; see e.g. [4, 11, 16, 17]. They are described by macroscopic equations and their appearance is usually, but not necessarily (cf. [12]) a consequence of certain good "ergodic" properties of the time evolution. One such condition, at least for mean field interactions, is the so-called propagation of chaos [3, 8, 10...
متن کاملماهیت ویژه حالتهای فونون در زنجیرهای شبه تناوبی( نقش شبکههای فیبوناچی )
Using the forced oscillator method (FOM) and the transfer-matrix technique, we numerically investigate the nature of the phonon states and the wave propagation, in the presence of an external force, in the chains composed of Fibonacci lattices of type site, bond and mixing models, as the quasiperiodic systems. Calculating the Lyapunov exponent and the participation ratio, we also study the lo...
