A Novel Mechanism for the Formation of Dislocation Cell Patterns in BCC Metal
Jaehyun Cho, Luke L. Hsiung, Robert E. Rudd +1
In this study, we present the first simulation results of the formation of dislocation cell wall microstructures in tantalum subjected to shock loading. Dislocation patterns and ce…
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,…
Using Conservation Laws to Infer Deep Learning Model Accuracy of Richtmyer-meshkov Instabilities
Charles F. Jekel, Dane M. Sterbentz, Sylvie Aubry +3
Richtmyer-Meshkov Instability (RMI) is a complicated phenomenon that occurs when a shockwave passes through a perturbed interface. Over a thousand hydrodynamic simulations were per…
Fast algorithms for evaluating the stress field of dislocation lines in anisotropic elastic media
C. Chen, S. Aubry, T. Oppelstrup +2
In dislocation dynamics (DD) simulations, the most computationally intensive step is the evaluation of the elastic interaction forces among dislocation ensembles. Because the pair-…
Computing forces on interface elements exerted by dislocations in an elastically anisotropic crystalline material
Bing Liu, Athanasios Arsenlis, Sylvie Aubry
Driven by the growing interest in numerical simulations of dislocation-interface interactions in general crystalline materials with elastic anisotropy, we develop algorithms for th…
Pressure Fronts in 1D Damped Nonlinear Lattices
S. Aubry, L. Proville
The propagation of pressure fronts (impact solutions) in 1D chains of atoms coupled by anharmonic potentials between nearest neighbor and submitted to damping forces preserving uni…
