Effects of a frictional interface on the load diffusion from a broken filament embedded in an elastic medium Academic Article uri icon

abstract

  • The effects of a frictional interface on the load diffusion from a broken fiber to the surrounding matrix material and the extent of debonding near the fiber break in a single-fiber reinforced composite of infinite extent are studied by using the finite element method. The numerically computed axial load carried by the fiber for the perfectly bonded case is first compared with analytical results. Then, the normal and shear stresses on the interface, the extent of the slip zone and the axial load of the fiber are evaluated for different factional coefficients and material parameters for both the fiber and the matrix. A shear-lag analysis is also carried out to obtain a closed form approximate solution of the fiber loud diffusion problem. The extent of the slip zone and the stresses predicted by the shear-lag model are compared with the finite element method results. © 1990.
