Abstract : This investigation is concerned with the interaction as far as loadabsorption is concerned of a pair of identical parallel elastic filaments in a fiberreinforced composite material. The filaments are assumed to have uniform circular cross sections, are taken to be semiinfinite, and are supposed to be continuously bonded to an allaround infinite matrix of distinct elastic properties. At infinity the matrix is subjected to uniaxial tension parallel to the filaments. Two separate but related problems are treated. In the first both filaments extend to infinity in the same direction and their terminal crosssections are coplanar. In the second problem the filaments extend to infinity in the same direction and their terminal crosssections need no longer be coplanar, the two filaments being permitted to overlap partly. An approximate scheme based in part on threedimensional linear elasticity and developed originally by Muki and Sternberg is employed in the analysis. The problems are ultimately reduced to Fredholm integral equations which characterize the distribution of the axial filament force. The integral equations are analyzed asymptotically and numerically. Results are presented which show the variation of filament force with position and the effect on this variation of various relevant geometrical and material parameters. (AuthorPL)
