Differences Between Coarse-Grained and Fine-Grained Soil

Coarse-grained soils have 50% or less material passing the No. 200 sieve. Fine-grained soils have 50% or more material passing the No. 200 sieve. Engineering properties such as strength and compressibility of coarse-grained soil are governed by the grain-size of the particles and their structural arrangement.

It should be noted that the GSD of coarse-grained materials is always changed with particle breakage. This phenomenon is unavoidable for rockfill materials when the consolidation pressure reaches 1.5 MPa, as mentioned in section 3.1. Once crushing, granular material behaviors would be dominated by not only initial GSD but also GSD evolution.

For multiscale modeling of biomolecules, reliable coarse-grained (CG) models can offer great potential to simulate larger temporal and spatial scales than traditional all-atom (AA) models. In this study, we explore the essential dynamics coarse graining (EDCG) and fixed-length coarse graining (FLCG) approaches for constructing highly coarse-grained models for multidomain proteins (MDPs), with ...

In CG-MD, one or more monomers/units of the hybrid materials are represented as a coarse-grained bead capable of reproducing parts of the polymer architecture. This leads to the loss of fine-grained atomic details of the system, which are crucial for studying properties and interactions of atom-level structures, but concurrently saves a ...

The low permeability of the top soil will cause the area around sidewalks to have poor drainage. The water clogged in the soil reduces its shear strength and consequently induces sidewalk damage. In order to improve permeability and shear strength, top soil can be mixed with a coarse-grained material, such as granite chips.
