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…
Asymmetric Roughness of Elastic Interfaces at the Depinning Threshold
Esko Toivonen, Matti Molkkari, Esa Räsänen +1
Roughness of driven elastic interfaces in random media is typically understood to be characterized by a single roughness exponent . We show that at the depinning threshold, due…
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…
Effect of thresholding on avalanches and their clustering for interfaces with long-range elasticity
Juha Savolainen, Lasse Laurson, Mikko Alava
Avalanches are often defined as signals higher than some detection level in bursty systems. The choice of the detection threshold affects the number of avalanches, but it can also…
