contact.engineering -- Create, analyze and publish digital surface twins from topography measurements across many scales
Michael C. Röttger, Antoine Sanner, Luke A. Thimons +6
The optimization of surface finish to improve performance occurs largely through trial and error, despite significant advancements in the relevant science. There are three central…
Nonequilibrium plastic roughening of metallic glasses yields self-affine topographies with strain-rate and temperature-dependent scaling exponents
Wolfram G. Nöhring, Adam R. Hinkle, Lars Pastewka
We study nonequilibrium roughening during compressive plastic flow of initially flat CuZr metallic glass using large-scale molecular dynamics simulations. Roughness e…
Scale-dependent roughness parameters for topography analysis
Antoine Sanner, Wolfram G. Nöhring, Luke A. Thimons +2
The failure of roughness parameters to predict surface properties stems from their inherent scale-dependence; in other words, the measured value depends on the way it was measured.…
Surface lattice Green's functions for high-entropy alloys
Wolfram Georg Nöhring, Jan Grießer, Patrick Dondl +1
We study the surface elastic response of pure Ni, the random alloy FeNiCr and an average FeNiCr alloy in terms of the surface lattice Green's function. We propose a scheme for comp…
Design using randomness: a new dimension for metallurgy
Wolfram Georg Nöhring, W. A. Curtin
High entropy alloys add a new dimension, atomic-scale randomness and the associated scale-dependent composition fluctuations, to the traditional metallurgical axes of time-temperat…
Correlation of microdistortions with misfit volumes in High Entropy Alloys
Wolfram Georg Nöhring, W. A. Curtin
The yield strengths of High Entropy Alloys have recently been correlated with measured picometer-scale atomic distortions. Here, the root mean square microdistortion in a multicomp…
The universal emergence of self-affine roughness from deformation
Adam R. Hinkle, Wolfram Nöhring, Lars Pastewka
Most natural and man-made surfaces appear to be rough on many length scales. There is presently no unifying theory of the origin of roughness or the self-affine nature of surface t…
