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.

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 ...

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.

Approach. Generate realistic models of austenitic welds and coarse-grain materials, including crystalline orientations (Euler angles). Evaluate beam simulations in CIVA, and compare results to empirical beam maps. Compare the beam simulations from realistic specimen models to those from simple structural models that are included with CIVA.

Particle breakage is commonly observed in coarse-grained materials (CGMs) when subjected to external loads. In this study, the evolution of the particle size distribution of CGMs was systematically investigated by conducting a series of impact loading tests with respect to different influencing factors: initial grading, water content, and compaction coefficient.

Below, we briefly describe these essential steps required for bottom-up CG modeling and discuss how they are related to the aforementioned challenges. 2-1. Coarse-Grained Mapping. The process of applying a CG mapping reduces the high-dimensional atomistic phase space to a low-dimensional CG phase space.
