Modeling the Elastic-Plastic Deformation of Al/Al2O3 Particulate Composites
Abstract:Comparison is made between experimental measurements of the elasticplastic deformation of a series of Al/Al2O3 particulate composites with a rather simple hybrid modeling method combining an effective medium approximation with the essential features of dislocation plasticity. Two different effective approximationsa simple, non-self-consistent and a self-consistent effective medium approximationare employed depending on the volume fraction of particles. For a wide range of volume fractions of Al2O3 particles, there is good agreement between the full stressstrain curves measured and the predictions of the hybrid model.
