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 fine grained soils, where the grains are smaller than 0.075 mm, the mineralogy of the soil grains, water content, etc. have greater influence than the grain sizes, on the engineering behaviour. The borderline between coarse and fine grained soils is 0.075 mm, which is the smallest grain size one can distinguish with naked eye.

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.

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.

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.

Backfill materials that are commonly used are described below with their engineering properties. 1. Coarse-grained soils. Coarse-grained soils include gravelly and sandy soils and range from clayey sands ( SC) through the well-graded gravels of gravel-sand mixtures ( GW) with little or no fines. They will exhibit slight to no plasticity.
