Frustrated junctions in interfacial networks
Håkan Hallberg, Vasily V. Bulatov, Bryan W. Reed +1
Networks of interfaces in materials and living systems evolve through motion and rearrangement of interfaces and junctions. Local equilibrium at a junction requires interfacial for…
Learning dislocation dynamics mobility laws from large-scale MD simulations
Nicolas Bertin, Vasily V. Bulatov, Fei Zhou
The computational method of discrete dislocation dynamics (DDD), used as a coarse-grained model of true atomistic dynamics of lattice dislocations, has become of powerful tool to s…
Score-based denoising for atomic structure identification
Tim Hsu, Babak Sadigh, Nicolas Bertin +4
We propose an effective method for removing thermal vibrations that complicate the task of analyzing complex dynamics in atomistic simulation of condensed matter. Our method iterat…
Enhanced mobility of dislocation network nodes and its effect on dislocation multiplication and strain hardening
Nicolas Bertin, Wei Cai, Sylvie Aubry +2
Understanding plastic deformation of crystals in terms of the fundamental physics of dislocations has remained a grand challenge in materials science for decades. To overcome this,…
Energy storage under high-rate compression of single crystal tantalum
Jared C. Stimac, Nicolas Bertin, Jeremy K. Mason +1
When a material is plastically deformed the majority of mechanical work is dissipated as heat, and the fraction of plastic work converted into heat is known as the Taylor-Quinney c…
Metal hardening in atomistic detail
Luis A. Zepeda-Ruiz, Alexander Stukowski, Tomas Oppelstrup +4
Through millennia humans exploited the natural property of metals to get stronger or hardened when mechanically deformed. Ultimately rooted in the motion of dislocations, mechanism…
