Due to the lack of water, only a very small amount of these molecules, striving for thermodynamical equilibrium, dissociates and supplies a few protons very close to the interface or in vicinity of etching-sensitive grain boundaries.
A simple computational model, predicated on the premise that a rate-sensitive grain-boundary affected zone exists, is shown to explain the observed effect of grain size on the rate-dependent plastic response.
The stochastic approaches adopted in the proposed model successfully capture the failure behavior of bimodal coppers that are sensitive to grain size and the volume fraction of coarse grains in addition to the corresponding threshold for percolation.
The hypothesis of a grain-boundary-diffusion process leading to cracking is supported, and the susceptibility to this type of cracking appears to be extremely sensitive to grain boundary structure.
The thermo-power (S) is less sensitive to grain boundaries and likely corresponds to the bulk properties.
In addition, since the computed properties are aggregates, as expected, we ensured that the results are not sensitive to grain boundary thickness.
Deb is sensitive to grains, GMO foods, preservatives and all artificial flavoring and coloring, so we ate cabbage soup for dinner.
Hence, in the range that we have explored, the granular impact dynamics are highly sensitive to grain-scale roughness of the intruder and relatively insensitive to microscale roughness that is associated with the conventional friction coefficient.
Diffusion creep is sensitive to mean grain size but insensitive to strain rate (n D = 1); dislocation creep is independent of grain-size but is non-Newtonian ; dislocation-accommodated grain-boundary sliding is both grain-size sensitive and non-Newtonian.
Detailed analysis of the lattice strain distributions reveal that {1 0 0} and {1 1 0} transverse families exhibit a bimodal nature, and that transverse lattice strains are more sensitive to local grain interactions compared with longitudinal lattice strains.
In general, these behaviors are sensitive to the grain boundary structure, making atomic-scale quantification of such parameters challenging due to the large number of variables in the input space of such a problem.
