Abstract When unperturbed, granular materials form stable structures that resemble the ones of other amorphous solids like metallic or colloidal glasses. Whether not under shear have an elastic response is known, and also influence particle surface roughness on yielding transition has so far remained elusive. Here we use X-ray tomography to determine three-dimensional microscopic dynamics two systems different are driven by cyclic shear. Both systems, for all amplitudes Γ considered, show a...
Cigarette butt (CB) waste is abundant and difficult to biodegrade, which dangerous for both the environment human health. The key reason CBs are littered that people do not know much about harm pose environment. Recycling in infrastructure construction can help raise people’s awareness. To promote recycling of CB waste, this paper aimed determine feasibility using as a modifier asphalt binders. In research, were preprocessed mixed with virgin binder fiber modifier. Comprehensive laboratory...
The quantification of styrene-butadiene-styrene (SBS) in modified asphalt is essential to evaluate the performance asphalt. In this work, Fourier transform infrared (FTIR) spectroscopy with solvent-cast film and chemometrics techniques, partial least squares (PLS) regression, have been implemented quantitatively analyse content SBS SBS-modified four different gradient as training samples specific testing sample scanned by FTIR spectrometer film. spectroscopic data measured analysed using PLS...
It is well established that the packing density (volume fraction) of random close packed (RCP) state congruent three-dimensional spheres, i.e., ${\ensuremath{\varphi}}_{c}\ensuremath{\sim}0.64$, can be improved by introducing particle size polydispersity. In addition, RCP ${\ensuremath{\varphi}}_{c}$ also increased perturbing shape from a perfect sphere to nonspherical shapes (e.g., superballs or ellipsoids). this paper, we numerically investigate coupling effects and on improving disordered...
Abstract This work explores the uplift history of best exposed marine terraces in northeastern Arabian Peninsula (eastern Al Hajar Mountains). A multidisciplinary approach was employed, including a topographic survey, 14 C dating, thin section studies, and scanning electron microscopy analyses. Six distinctive with widths ranging from tenth meters to kilometers elevations 5 ~400 m were studied. These record an along-strike heterogeneous history, while they show temporally variable rates...
Using x-ray tomography, we experimentally investigate granular packings subject to mechanical tapping for three types of beads with different friction coefficients. We validate the Edwards volume ensemble in these three-dimensional systems and establish a version thermodynamic zeroth law. Within framework, also explicitly clarify how influences statistical mechanics by modifying density states, which allows us determine entropy as function packing fraction friction. Additionally, obtain...
As bitumen from different manufacturers exhibit properties, which may impact on the performance of asphalt pavement, currently it is necessary to implement appropriate methods in order classify or identify source bitumen. In this work, 15 samples three were collected and analysed by attenuated total reflectance Fourier transform infrared (ATR-FTIR). The spectrum data pretreatment principal component analysis (PCA). PCA score plot reveals that successfully solved distinct regions, each...
We carry out numerical studies of both amorphous and ordered packings frictionless superellipsoidal particles in three spatial dimensions to understand their structural mechanical properties.
Cylindrical particles are ubiquitous in nature and industry, a cylinder is representative shape of rod-like particles. However, the disordered packing results cylinders previous studies quite inconsistent with each other. In this work, we obtain MRJ (maximally random jammed) packings MDRPs dense packings) perfect aspect ratio (height/diameter) 0.2 ≤ w 6.0 using ASC (adaptive shrinking cell) algorithm IMC (inverse Monte Carlo) method, respectively. The optimal corresponding to maximal density...
An ellipsoid, the simplest nonspherical shape, has been extensively used as a model for elongated building blocks wide spectrum of molecular, colloidal, and granular systems. Yet densest packing congruent hard ellipsoids, which is intimately related to high-density phase many condensed matter systems, still an open problem. We discover unusual family dense crystalline packings self-dual ellipsoids (ratios semiaxes $\ensuremath{\alpha}:\sqrt{\ensuremath{\alpha}}:1$), containing 24 particles...
Understanding disordered particle packings is of great significance from both theoretical and engineering perspectives. Establishing a quantitative relationship between nonspherical shape packing properties generally challenging, due to the complex geometry topology. Here we resolve this issue by numerically investigating jammed various frictional congruent particles, including superellipsoids polyhedra, over wide range friction coefficients. We discover several universal characteristics...
