Samenvatting

The thrust of this paper is that micromechanics goes beyond homogenization when it is regarded as a multiscale modeling approach. Using metal plasticity as an example, the paper illustrates how macroscopic irreversibility is a natural consequence of emergent behaviour in space and in time. Special attention is given to the currently weak link between discrete dislocation plasticity and continuum crystal plasticity, and how dislocation interactions give rise to powerlaw viscoplasticity. As an outlook it is suggested that, by enlarging its missionto coarse graining in space and time, micromechanics can play an importantrole in the understanding and description of new supramolecular materials.
