ELASTIC MODULUS AND YIELD STRENGTH OF SHORT FIBER REINFORCED METAL MATRIX COMPOSITES

The expressions for the elastic modulus and the yield strength of the composite were derived based on the deformation model and the results of the stress analysis. The predictions of the expressions exhibit good agreement with the experiments and also with those from the Eshelby model and finite element numerical calculations. It was shown that the increased elastic modulus and yield strength relative to the elastic modulus and the yield strength of the matrix depend mainly on the contribution from the stress transfer.
