Avalanche correlations and stress-strain curves in discrete dislocation plasticity
Henri Salmenjoki, Lasse Laurson, Mikko J. Alava
The sequence of deformation bursts during plastic deformation exhibits scale-free features. In addition to the burst or avalanche sizes and the rate of avalanches the process is ch…
Probing the transition from dislocation jamming to pinning by machine learning
Henri Salmenjoki, Lasse Laurson, Mikko J. Alava
Collective motion of dislocations is governed by the obstacles they encounter. In pure crystals, dislocations form complex structures as they become jammed by their anisotropic she…
Plastic yielding and deformation bursts in the presence of disorder from coherent precipitates
Henri Salmenjoki, Arttu Lehtinen, Lasse Laurson +1
Alloying metals with other elements is often done to improve the material strength or hardness. A key microscopic mechanism is precipitation hardening, where precipitates impede di…
Machine learning plastic deformation of crystals
Henri Salmenjoki, Mikko J. Alava, Lasse Laurson
Plastic deformation of micron-scale crystalline solids exhibits stress-strain curves with significant sample-to-sample variations. It is a pertinent question if this variability is…
Mimicking complex dislocation dynamics by interaction networks
Henri Salmenjoki, Mikko J. Alava, Lasse Laurson
Two-dimensional discrete dislocation models exhibit complex dynamics in relaxation and under external loading. This is manifested both in the time-dependent velocities of individua…
