摘要：

The bulk and shear modulus of metal matrix composites with various volume fractions of particles are modified based on the Eshelby's equivalent inclusion method combined with self-consistent scheme. By introducing the modified modulus, a new model, which can predict the particle size effects on the stress-strain relation under interfacial debonding damage between matrix and particles, is established. The results obtained from the present investigation show a better agreement with the experimental data.
