The random packing density of nearly spherical particles.
Obtaining general relations between macroscopic properties of random assemblies, such as density, and the microscopic properties of their constituent particles, such as shape, is a foundational challenge in the study of amorphous materials. By leveraging existing understanding of the random packing of spherical particles, we estimate the random packing density for all sufficiently spherical sha...
متن کاملMorphology-dependent resonances of nearly spherical particles in random orientation.
We use precise T-matrix calculations for prolate and oblate spheroids, Chebyshev particles, and spheres cut by a plane to study the evolution of Lorenz-Mie morphology-dependent resonances (MDRs) with increasing asphericity of nearly spherical particles in random orientation. We show that, in the case of spheroids and Chebyshev particles, the deformation of a sphere by as little as one hundredth...
متن کاملllenges in packing problems: from spherical to non-spherical particles
HIGHLIGHT Adrian Baule and Hernán A. Makse Fundamental challenges in packing problems: from spherical to non-spherical particles Random packings of objects of a particular shape are ubiquitous in science and engineering. However, such jammed matter states have eluded any systematic theoretical treatment due to the strong positional and orientational correlations involved. In recent years progre...
متن کاملFractal Properties of Dense Packing of Spherical Particles
Two computer models were developed to realize the algorithms of random Apollonian and Apollonian packings of the spherical particles in a unit cube. A genetic algorithm was developed for the latter packing model. The upper and lower bounds of a fractal dimension were computed using various numerical methods. It was observed that for both models the fractal properties were not essentially affect...
