Effects of the grain size and shape on the flow stress: A dislocation dynamics study [PDF]

International Journal of Plasticity, 2019
Dislocation dynamics simulation is used to investigate the effect of grain size and grain shape on the flow stress in model copper grains. We consider grains of 1.25-10 $\mu$m size, three orientations (, and ) and three shapes (cube, plate and needles).

A high-resolution genotype–phenotype map identifies the TaSPL17 controlling grain number and size in wheat

Genome Biology, 2023
Background Large-scale genotype–phenotype association studies of crop germplasm are important for identifying alleles associated with favorable traits.

Influence of grain size on strength of polymineralic crystalline rock: New insights from DEM grain-based modeling

Journal of Rock Mechanics and Geotechnical Engineering, 2021
Grain size effect on rock strength is a topic of great interest in geotechnical engineering. A consensus obtained from earlier laboratory tests is that rock strength generally decreases with the increase of grain size for both silicate and carbonate ...

Numerical simulation of grain-size effects on creep crack growth by means of grain elements [PDF]

, 1998
The effect of grain size on creep crack growth is investigated by means of a numerical technique in which the actual crack growth process is simulated in a discrete manner by grain elements and grain boundary elements.

Sensitive Grain-Size Components of Last Glacial Loess on Chinese Loess Plateau and Their Response to East Asian Winter Monsoon

Atmosphere, 2023
Chinese loess provides the most detailed terrestrial records of paleoclimate changes. We employed the grain-size components of aeolian sediments to reconstruct the history of the East Asian winter monsoon (EAWM) on the Chinese Loess Plateau (CLP).

Synthesized grain size distribution in the interstellar medium [PDF]

, 2012
We examine a synthetic way of constructing the grain size distribution in the interstellar medium (ISM). First we formulate a synthetic grain size distribution composed of three grain size distributions processed with the following mechanisms that govern

Grain size reduction strategies on Eurofer

Nuclear Materials and Energy, 2018
One of the options currently taken into account for the realization of the first DEMO reactor is the “water-cooled blanket”. This option implies a minimum irradiation temperature for the blanket material in the range of 280–350 °C.

Fast Image Classification for Grain Size Determination

Metals, 2021
With the increasing application of steel materials, the metallographic analysis of steel has gained importance. At present, grain size analysis remains the task of experts who must manually evaluate photos of the structure.

Explaining International Variance in Foreign Bribery Prosecution: A Comparative Case Study [PDF]

, 1996
Ion plating is essentially vapor deposition onto a substrate which is the cathode of a glow discharge. The most important characteristic of the technique is that the growing film is subjected to a flux of high energy particles (neutrals and ions).
