Propagating bands of plastic deformation in a metal alloy as critical avalanches
Tero Mäkinen, Pasi Karppinen, Markus Ovaska +2
The plastic deformation of metal alloys localizes in the Portevin--Le Chatelier effect in bands of different types, including propagating, or type 'A' bands, usually characterised…
Excitation spectra in crystal plasticity
Markus Ovaska, Arttu Lehtinen, Mikko J. Alava +2
Plastically deforming crystals exhibit scale-free fluctuations that are similar to those observed in driven disordered elastic systems close to depinning, but the nature of the yie…
Deformation and fracture of echinoderm collagen networks
Markus Ovaska, Zsolt Bertalan, Amandine Miksic +8
Collagen networks provide the main structural component of most tissues and represent an important ingredient for bio-mimetic materials for bio-medical applications. Here we study…
Avalanches in wood compression
Tero Mäkinen, Amandine Miksic, Markus Ovaska +1
Wood is a multi-scale material exhibiting a complex viscoplastic response. We study avalanches in small wood samples in compression. "Woodquakes" measured by acoustic emission are…
Quenched pinning and collective dislocation dynamics
Markus Ovaska, Lasse Laurson, Mikko J. Alava
Several experiments show that crystalline solids deform in a bursty and intermittent fashion. Power-law distributed strain bursts in compression experiments of micron-sized samples…
