PHYS brown bag seminar: Machine learning plastic deformation of crystals

Presenter: Henri Salmenjoki (CSM group)

Abstract: 

The irreversible changes in crystalline materials during plastic deformation are governed by the motion of dislocations – the line defects of the crystal structure. Experiments have shown that plastic deformation progresses through bursty events and in micron-scale samples these avalanches cause the stress-strain response to fluctuate drastically from sample to sample. Here our aim was to study if the stress response of a simulated system could be predicted from the initial dislocation configuration.
