A Rich Example of Geometrically Induced Nonlinearity: From Rotobreathers and Kinks to Moving Localized Modes and Resonant Energy Transfer
P. G. Kevrekidis, S. V. Dmitriev, S. Takeno +2
We present an experimentally realizable, simple mechanical system with linear interactions whose geometric nature leads to nontrivial, nonlinear dynamical equations. The equations…
Statistical Analysis for Long Term Correlations in the Stress Time Series of Jerky Flow
Dimitris Kugiumtzis, Elias C. Aifantis
Stress time series from the PLC effect typically exhibit stick-slips of upload and download type. These data contain strong short-term correlations of a nonlinear type. We investig…
Self-affine surface morphology of plastically deformed metals
Michael Zaiser, Frederic Maqdani, Vasileios Koutsos +1
We analyze the surface morphology of metals after plastic deformation over a range of scales from 10 nm to 2 mm, using a combination of atomic force microscopy and scanning white-l…
