Optimal FFT-accelerated Finite Element Solver for Homogenization
Martin Ladecký, Richard J. Leute, Ali Falsafi +4
We propose a matrix-free finite element (FE) homogenization scheme that is considerably more efficient than generic FE implementations. The efficiency of our scheme follows from a…
Comprehensive topography characterization of polycrystalline diamond coatings
Abhijeet Gujrati, Antoine Sanner, Subarna R. Khanal +4
The surface topography of diamond coatings strongly affects surface properties such as adhesion, friction, wear, and biocompatibility. However, the understanding of multi-scale top…
Solid-phase silicon homoepitaxy via shear-induced amorphization and recrystallization
Thomas Reichenbach, Gianpietro Moras, Lars Pastewka +1
The development of epitaxy techniques for localized growth of crystalline silicon nanofilms and nanostructures has been crucial to recent advances in electronics and photonics. A p…
Quantitative prediction of the fracture toughness of amorphous carbon from atomic-scale simulations
S. Mostafa Khosrownejad, James R. Kermode, Lars Pastewka
Fracture is the ultimate source of failure of amorphous carbon (a-C) films, however it is challenging to measure fracture properties of a-C from nano-indentation tests and results…
Constitutive relations for plasticity of amorphous carbon
Richard Jana, Julian von Lautz, S. Mostafa Khosrownejad +3
We deform representative volume elements of amorphous carbon obtained from melt-quenches in molecular dynamics calculations using bond-order and machine learning interatomic potent…
Structural and elastic properties of amorphous carbon from simulated quenching at low rates
Richard Jana, Daniele Savio, Volker L. Deringer +1
We generate representative structural models of amorphous carbon (a-C) from constant-volume quenching from the liquid with subsequent relaxation of internal stresses in molecular d…
