Ananthakrishna, G (2005) A dynamical approach to the spatio-temporal features of the Portevin-Le Chatelier effect. In: Computer Modeling in Engineering and Sciences (CMES), 7 (3). pp. 233-239.Full text not available from this repository.
We show that the extended Ananthakrishna's model exhibits all the features of the Portevin - Le Chatelier effect including the three types of bands. The model reproduces the recently observed crossover from a low dimensional chaotic state at low and medium strain rates to a high dimensional power law state of stress drops at high strain rates. The dynamics of crossover is elucidated through a study of the Lyapunov spectrum.
