Abstract

Established experimental results indicate that material deformation is often jerky with discrete events occurring in a stochastic manner. In micron-sized material volumes, such discrete events may correspond to very large strain changes so that the overall behaviour may no longer be describable by smooth constitutive laws. In this paper, the corresponding experimental observations are surveyed. The stochastic and jerky nature of the plastic events calls for new approaches to model plasticity in small volumes, and attempts based on statistical ensembles are discussed.
