Hard hadronic diffraction is not hard [PDF]

open access: yesInternational Journal of Modern Physics E, 2016
Hadronic diffractive processes characterized by a hard scale (hard diffraction) contain a nontrivial interplay of hard and soft, nonperturbative interactions, which breaks down factorization of short and long distances. On the contrary to the expectations based on the factorization hypothesis, assuming that hard diffraction is a higher twist, these ...

Polydisperse hard spheres at a hard wall [PDF]

open access: yesThe Journal of Chemical Physics, 2004
The structural properties of polydisperse hard spheres in the presence of a hard wall are investigated via Monte Carlo simulation and density functional theory (DFT). Attention is focused on the local density distribution ρ(σ,z), measuring the number density of particles of diameter σ at a distance z from the wall.

Hardness relationship between eNM3A10 and conventional hardness scales

open access: yesMeasurement: Sensors, 2021
Small ball rebound hardness eNM3A10 is a next-generation rebound hardness test with features not existing in conventional rebound hardness tests: reduced mass effect of hardness and satisfying the similarity rule of hardness (Minimum thickness of steel ...

Analysis of indentation size effect in copper and its alloys [PDF]

open access: yes, 2013
For describing the indentation size effect (ISE), numerous models, which relate the load or hardness to the indent dimensions, have been proposed. Unfortunately, it is still difficult to associate the different parameters involved in such relationships ...

Conventional Vickers and true instrumented indentation hardness determined by instrumented indentation tests [PDF]

open access: yes, 2010
We evaluate Vickers hardness and true instrumented indentation test (IIT) hardness of 24 metals over a wide range of mechanical properties using just IIT parameters by taking into account the real contact morphology beneath the Vickers indenter ...
