Avalanches in 2D Dislocation Systems: Plastic Yielding is not Depinning
Péter Dusán Ispánovity, Lasse Laurson, Michael Zaiser +3
We study the properties of strain bursts (dislocation avalanches) occurring in two-dimensional discrete dislocation dynamics models under quasistatic stress-controlled loading. Con…

Average yielding and weakest link statistics in micron-scale plasticity
Péter Dusán Ispánovity, Ádám Hegyi, István Groma +3
Micron-scale single crystalline materials deform plastically via large intermittent strain bursts that make the deformation process unpredictable. Here we investigate this stochast…
