Sliding and rolling grains remain in continuous contact with the bed, while suspended particles have little or no contact with the bed.
Reid and Frostick (1994) defined the bedload as the grains that move along the bed and that are essentially in contact with it at all times (i.e., including only sliding and rolling particles) and independently defined the saltation load; however, others (e.g., Allen 1982; Bridge and Demicco 2008) defined the bedload to include saltating grains in addition to sliding and rolling grains.
The study aims to investigate the influence of the grain morphology and rolling texture on the fatigue crack initiation in BCC polycrystals.
The region RM314 on chromosome 6 explained a higher proportion of phenotypic variation for both leaf rolling and grain yield in drought stress conditions.
This behaviour is clearly shown in the details of Fig. 5, where a growing grain (grain 2) splits a grain (grain 1 in detail A, B) first, followed by a possible disappearance during further cold-rolling (grain 1 in detail B).
Cracks on the alloy surface were initiated mainly at grain boundaries due to rolling stresses and grain boundary sliding, causing an overlapping of grains.
Posada then smashed a liner past Alfonzo, the ball rolling against the grain of the defense, going between the outfielders for a double, Martinez stopping at third.
To simulate the behavior of sand, the three-dimensional spherical discrete model was used allowing for grain rolling resistance.
The objectives of this study were to evaluate the effects of volume weight (VW; g/L), processing method (PM; control vs. precision processing [PP]), and processing index (PI; VW after rolling/VW before rolling) of barley grain on in situ ruminal kinetics and in vitro intestinal digestion.
A GPU-based two-dimensional discrete element methodology allowing for grain rolling resistance is adopted to study the engineering and fundamental aspects of shear band formation in normal and reverse faulting through an initially dense sand; of course, the paper emphasizes on fundamental aspects.
