Abstract: Based on the energy equivalence principle, the elastic modulus of Al₂O₃f/Al composite was predicted by means of the Finite Element Method. In the predicting, the random orientation distribution of short fiber was considered. The results were compared with the experimental values and those of previous predicting methods. In the end, it can be concluded that the method developed in this paper is reasonable and precise.
