LEFM is agnostic to geometrical nonlinearities arising at atomistic crack tips
Tarakeshwar Lakshmipathy, Paul Steinmann, Erik Bitzek
Various fields such as mechanical engineering, materials science, etc., have seen a widespread use of linear elastic fracture mechanics (LEFM) at the continuum scale. LEFM is also…
A new method for microscale cyclic crack growth characterization from notched microcantilevers and application to single crystalline tungsten and a metallic glass
S. Gabel, B. Merle, E. Bitzek +1
The lifetime of most metals is limited by cyclic loads, ending in fatigue failure. The progressive growth of cracks ends up in catastrophic failure. An advanced method is presented…
Systematic Atomic Structure Datasets for Machine Learning Potentials: Application to Defects in Magnesium
Marvin Poul, Liam Huber, Erik Bitzek +1
We present a physically motivated strategy for the construction of training sets for transferable machine learning interatomic potentials. It is based on a systematic exploration o…
The Origin of Deformation Induced Topological Anisotropy in Silica Glass
Sudheer Ganisetti, Achraf Atila, Julien Guénolé +4
Oxide glasses with a network structure are omnipresent in daily life. Often, they are regarded as isotropic materials; however, structural anisotropy can be induced through process…
Unveiling the mechanisms of motion of synchro-Shockley dislocations in Laves phases
Zhuocheng Xie, Dimitri Chauraud, Achraf Atila +3
In Laves phases, synchroshear is the dominant basal slip mechanism. It is accomplished by the glide of synchro-Shockley dislocations. However, the atomic-scale mechanisms of motion…
Structural reorientation and compaction of porous MoS2 coatings during wear testing
Sebastian Krauß, Armin Seynstahl, Stephan Tremmel +7
Industrial upscaling frequently results in a different coating microstructure than the laboratory prototypes presented in the literature. Here, we investigate the wear behavior of…
