Abstract
An experimental time series from a tensile test of an Al-Mg alloy in t he serrated plastic flow domain is analyzed for signature of chaos. We employ state space reconstruction by embedding of time delay vectors. The minimum embedding dimension is found to be 4 and the largest Lyap unov exponent is positive, thereby providing prima facie evidence for chaos in an experimental time series of serrated plastic flow data.
