| Abstract: | The Eshelby theory combined with Mori-Tanaka approach is presented for investigating the evolution of microcracks and its effect on the mechanical properties of fiber composites. The variation of matrix cracking strength with fiber volume fraction, fiber elastic constant, microcrack density and the various direction of fiber is analyzed. Some useful results are suggested. |
