In the present paper, the effects of fillers on the characteristics of dispersion strengthened composite materials (DSCM) are considered theoretically assuming that the filler particles are elliptic. The theoretical results show that the Young's modulus of DSCM is dependent on the shape and orientation of the particles as well as the volume loading. In order to prove the results, numerical calculations are performed by F. E. M. for some DSCM models, in which the position of particles is determined with random number table so that the particles are randomly distributed. The shape of the particles is assumed to be square and rectangular. Evperimental studies are also performed on the DSCM specimens made of epoxy and steel particles, and their Young's moduli are mesured. They show good agreement between experimental and numercal results.
