Abstract  The expressions for estimating fracture toughness of the polycomponent composite materials have been derived in terms of the fracture toughnesses and the volume fractions of individual component each is included. The expression, conformed to mixed rule, of upper (n→) or lower (n=1) bound value was also derived on the basis of limit analysis.
