The fundamental aspect of composites is that of stress transfer from the matrix to the fibers, and a number of mechanisms derive from this basic consideration. A previous analysis, although relatively simple and elegant, has a basic flaw, in that it assumes that there is no adhesion between the fiber and the matrix at the fiber ends, leading to the sometimes erronous condition of no stress transfer through those points. In this paper a modified end condition that better describes stress transfer is investigated and applied in determining the development of fiber, matrix and interfacial shear stress distribution in the uncracked, singly cracked and multiple cracked matrix configurations, with emphasis on the effects due to constituent dimensions.
