| Abstract | The axisymmetric problem of a crack in an infinitely long elastic fiber embedded in an infinite elastic matrix, subjected to longitudinal tensile strain, is analyzed within the framework of linear elastic fracture mechanics (LEFM). Perfect bonding is assumed at the fiber-matrix interface. Integral transform techniques are used to formulate the given problem in terms of a singular integral equation with a Cauchy type kernel which is then solved numerically. In this study four possible crack configurations are considered to obtain the stress intensity factors for a wide range of crack sizes and different ratios of shear moduli as follows: (a) annular crack with outer crack tip away from the interface ; (b) annular crack with outer crack tip at the interface; (c) penny-shaped crack with crack tip away from the interface; (d) penny-shaped crack with crack tip at the inte1face (fully cracked fiber). It is shown that the crack size, the ratio of shear moduli and the position of the crack tip from the fiber-matrix interface have a significant affect on the stress intensity factors at the crack tips. When the crack tip terminates at the interface, the characteristic equation is used to determine the order of the singularity. |
