The behaviour of dry and cohesionless sand body in a cyclic interface shear box test under a constant normal stiffness (CNS) condition is numerically studied. Do this end finite element calculations are carried out using a micro-polar hypoplastic model, where the mean grain diameter of the sand material is used as a characteristic length of the micro-structure. The constitutive equations for th...

We present fundamental and quantitative comparisons between the techniques of porometry (or flow permporometry), porosimetry, image analysis and void network modelling for seven types of filter, chosen to encompass the range of simple to complex void structure. They were metal, cellulose and glass fibre macroand meso-porous filters of various types. The comparisons allow a general reappraisal o...

We study the effect of two Modified Gravity (MG) theories, $f(R)$ and nDGP, on three probes large-scale structure, real space power spectrum estimator $Q_0$, bispectrum voids, validate fast approximate COLA simulations against full $N$-body for prediction these probes. find that using first even multipoles redshift to estimate $Q_0$ is enough reproduce MG boost factors both halo galaxy catalogu...

We analyze the mechanisms underlying the deformation of a nanovoid in an Al crystal subjected to cyclic shear deformation using numerical simulations. Boundary and cell-size effects have been minimized by means of the quasicontinuum method. The deformation of the void entails a noticeable reduction in volume. During the loading phase, our analysis reveals several stages of stress buildup separa...

with the expanding demand on application of magnesium alloys in automotive and aerospace industries, robust methods in fatigue characterization of commercially available magnesium alloys with high specific strength is anticipated. in this paper, rotating bending load controlled tests has been studied on specimens machined from an extrusion piece of az31b. due to asymmetric and anisotropic behav...
