Bayesian optimization of discrete dislocation plasticity of two-dimensional precipitation hardened crystals
Mika Sarvilahti, Lasse Laurson
Discovering relationships between materials' microstructures and mechanical properties is a key goal of materials science. Here, we outline a strategy exploiting Bayesian optimizat…
Barkhausen noise from formation of 360 domain walls in disordered permalloy thin films
Sami Kaappa, Lasse Laurson
Barkhausen noise in disordered ferromagnets is typically understood to originate primarily from jerky field-driven motion of domain walls. We study the magnetization reversal proce…
Avalanches and rate effects in strain-controlled discrete dislocation plasticity of Al single crystals
David Kurunczi-Papp, Lasse Laurson
Three-dimensional discrete dislocation dynamics simulations are used to study strain-controlled plastic deformation of face-centered cubic aluminium single crystals. After describi…
Machine learning reveals strain-rate-dependent predictability of discrete dislocation plasticity
Marcin Mińkowski, David Kurunczi-Papp, Lasse Laurson
Predicting the behaviour of complex systems is one of the main goals of science. An important example is plastic deformation of micron-scale crystals, a process mediated by collect…
Dislocation avalanches from strain-controlled loading: A discrete dislocation dynamics study
David Kurunczi-Papp, Lasse Laurson
We study strain-controlled plastic deformation of crystalline solids via two-dimensional discrete dislocation dynamics simulations. To this end, we characterize the average stress-…
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…
