Avalanches, precursors and finite size fluctuations in a mesoscopic model of amorphous plasticity
Mehdi Talamali, Viljo Petäjä, Damien Vandembroucq +1
We discuss avalanche and finite size fluctuations in a mesoscopic model to describe the shear plasticity of amorphous materials. Plastic deformation is assumed to occur through ser…
Strain localization and anisotropic correlations in a mesoscopic model of amorphous plasticity
Mehdi Talamali, Viljo Petäjä, Damien Vandembroucq +1
A mesoscopic model for shear plasticity of amorphous materials in two dimensions is introduced, and studied through numerical simulations in order to elucidate the macroscopic (lar…
Ground-States of Two Directed Polymers
V. T. Petaja, M. J. Alava, H. Rieger
Joint ground states of two directed polymers in a random medium are investigated. Using exact min-cost flow optimization the true two-line ground-state is compared with the single…
Disorder, Order, and Domain Wall Roughening in the 2d Random Field Ising Model
E. T. Seppala, V. Petaja, M. J. Alava
Ground states and domain walls are investigated with exact combinatorial optimization in two-dimensional random field Ising magnets. The ground states break into domains above a le…
