Abstract
We report new results on a dynamical model of serrated yielding. These essentially pertain to the full spectrum of Lyapunov exponents of the non-linear (chaotic) model and fractal characterization of the associ ated strange attractor. The power spectrum of scalar time series extra cted from the phase space trajectories decays exponentially with incre ase of frequency and the decay constant is found proportional to the K olmogorov-Sinai entropy.
