Inferring Dislocation Microstructures from X-ray Diffraction via Cross-Modal Contrastive Learning
Benjamin Udofia, Nicolas Bertin, Markus Stricker
Understanding and inferring dislocation microstructures from diffraction patterns remains an open challenge in materials characterization, as diffraction measurements provide only…
Link Statistics of Dislocation Network during Strain Hardening
Sh. Akhondzadeh, Hanfeng Zhai, Wurong Jian +3
Dislocations are line defects in crystals that multiply and self-organize into a complex network during strain hardening. The length of dislocation links, connecting neighboring no…
Computing virtual dark-field X-ray microscopy images of complex discrete dislocation structures from large-scale molecular dynamics simulations
Yifan Wang, Nicolas Bertin, Dayeeta Pal +4
Dark-field X-ray Microscopy (DFXM) is a novel diffraction-based imaging technique that non-destructively maps the local deformation from crystalline defects in bulk materials. Whil…
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,…
