From Brittle to Ductile Fracture in Disordered Materials
Clara B. Picallo, Juan M. López, Stefano Zapperi +1
We introduce a lattice model able to describe damage and yielding in heterogeneous materials ranging from brittle to ductile ones. Ductile fracture surfaces, obtained when the syst…
Adaptive Oscillator Networks with Conserved Overall Coupling: Sequential Firing and Near-Synchronized States
Clara B. Picallo, Hermann Riecke
Motivated by recent observations in neuronal systems we investigate all-to-all networks of non-identical oscillators with adaptive coupling. The adaptation models spike-timing-depe…
Optimization and plasticity in disordered media
Clara B. Picallo, Juan M. Lopez, Stefano Zapperi +1
We study the plastic yielding of disordered media using the perfectly plastic random fuse model. The yield surfaces are shown to be different from those obtained minimizing the sum…
Energy dissipation statistics in the random fuse model
Clara B. Picallo, Juan M. Lopez
We study the statistics of the dissipated energy in the two-dimensional random fuse model for fracture under different imposed strain conditions. By means of extensive numerical si…
