Title:Plasticity and criticality
Seminar:Applied Analysis Seminar
Speaker:Lev Truskinovsky, Harward University/Ecole Polytechnique
Abstract:
Power law fluctuations and scale free spatial patterns are known to characterize steady state plastic flow in crystalline materials. To study the emergence of correlations in plastic flow we study a simple 2D model which is largely free of arbitrariness, amenable to analytical study and is capable of generating critical exponents matching experiments. Our main observation concerns the possibility to reduce continuum plasticity to an integer valued automaton revealing inherent discreetness of the plastic flow.
