On the basis of the extent of coarse-graining, the systemic CG methods are roughly divided into three major classes: (i) low coarse-graining degrees, with one or two monomers in one bead, e.g., DBI and IBI schemes and MARTINI approach; (ii) medium coarse-graining degrees, having 10–20 monomers in one bead, e.g., blob model; and (iii) high coarse-graining degrees, having the whole chain ...

Then, a state-dependent bounding surface model for coarse-grained materials has been proposed, highlighting the effect of initial GSD. The high accuracy of this model is evidenced by a good agreement between the modelling results and the experimental counterparts under drained and undrained conditions.

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.

Coarse-grained modeling, coarse-grained models, aim at simulating the behaviour of complex systems using their coarse-grained (simplified) representation.

Coarse-grained materials (CGMs), including gravel, ballast, and rockfill material, exhibit a complicated stress-strain-volume change behavior, which is state dependent and influenced by considerable particle breakage even under relatively low pressure.

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.

Enhancing Coarse-Grained Models through Machine Learning

We introduce a general framework for constructing coarse-grained potential models without ad hoc approxns. such as limiting the potential to two- and/or three-body contributions. The scheme, called the Deep Coarse-Grained Potential (abbreviated DeePCG), exploits a carefully crafted neural network to construct a many-body coarse-grained potential.
