Avalanche localization and crossover scaling in amorphous plasticity / S. Budrikis, S. Zapperi. - In: PHYSICAL REVIEW E, STATISTICAL, NONLINEAR, AND SOFT MATTER PHYSICS. - ISSN 1539-3755. - 88:6(2013 Dec 10), pp. 062403.1-062403.7. [10.1103/PhysRevE.88.062403]
Abstract:
We perform large-scale simulations of a two-dimensional lattice model for amorphous plasticity with random local yield stresses and long-range quadrupolar elastic interactions. We show that as the external stress increases towards the yielding phase transition, the scaling behavior of the avalanches crosses over from mean-field theory to a different universality class. This behavior is associated with strain localization, which significantly depends on the short-range properties of the interaction kernel.
