| Abstract: | In present research, the effective properties of the composites for the pure shear case will be investigated. Based on the micromechanical model of single_fiber composites, the work is extended to composites reinforced by fiber bundles. The plane strain models for 3_fiber bundle and 4_fiber bundle composites are studied. The effective elasto_plastic properties are predicted numerically for boron/aluminum composites. |
