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…
Modelling aerosol transport and virus exposure with numerical simulations in relation to SARS-CoV-2 transmission by inhalation indoors
Ville Vuorinen, Mia Aarnio, Mikko Alava +27
We provide research findings on the physics of aerosol dispersion relevant to the hypothesized aerosol transmission of SARS-CoV-2. We utilize physics-based modeling at different le…
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…
