Improvement of Discrete Element Simulation Accuracy of Steel Powder Filling Behavior by Optimization of Contact and Friction Parameters

open access: yesTribology Online, 2021
The filling behavior of Fe-Ni-Mo steel powder for sintered machine parts is simulated using our original DEM (Discrete Element Method) code based on FDPS (Framework for Developing Particle Simulator). The difference between the simulated and experimental

Are Large Particles of Iron Detrimental to Properties of Powder Metallurgy Steels?

open access: yesMetals, 2020
It is experimentally shown that a removal of particles exceeding 100 microns in size from iron powders typically used in the fabrication of medium density powder metallurgy steels has a weak effect on apparent density, flowability and compressibility of

The valuation of the apparent density of a filter on a bicolored background [PDF]

open access: yesPerception & Psychophysics, 1985
When the transmittance of a filter on a bicolored background is varied, the lightness differences that vary are those between the filter and the background and that between the parts inside the filter. It is hypothesized that these are the differences of importance for the valuation of the apparent density of the transparent layer.

Fractal Dimensions of Cell Wall in Growing Cotton Fibers

open access: yesFractal and Fractional, 2020
In this research, fractal properties of a cell wall in growing cotton fibers were studied. It was found that dependences of specific pore volume (P) and apparent density (ρ) on the scale factor, F = H/h, can be expressed by power-law equations: P ...
