Abstract
When using metals and polymers in structural applications the macroscopic behavior depends on events taking place at levels in micrometer and nanometer ranges. At this range, material behavior, phenomena such as plasticity and fracture are size-dependent. We discuss these phenomena with regards to the case analyzed in this paper. Continuum mechanics flow theory of plasticity cannot explain the failure behavior of a particle-reinforced aluminum composite. An experimental study of the strain field in the micrometer range provides an explanation of the earlier than expected failure of the composite. We give a detailed description of the optical technique used to make the experimental mechanics measurements.
