Abstract : This study deals with the problem optimising grain dispersed and fiber reinforced material structures. The optimization procedure is presented for the cases of the minimum weight and the maximum stiffness designs of structures. In these cases the design variables are volume percents of grain or fiber in several parts of structure and it is subjected to strength or volume constraint. The relations between the design variables and the mechanical properties of composite materials are very important to formulate the design probelms.
