초록정보

A inclined edge crack in bonded elastic half plane under out-of-plane loading is analyzed. An edge crack with length b is inclined at an angle of ω with respect to the interface of material 1 and 2, shear modulus of which are $μ_1$ and $μ_2$, respectively. Two concentrated out-of-plane loads Q and R, on the free surface, are applied at the points of distance ℓ and h from the apex of the interface respectively. Introducing a displacement perpendicular to the surface and formulating the problem by Mellin transform, a Wiener-Hopf equation is derived. Solving the equation by Wiener-Hopf technique, a closed form solution for the displacement around the crack tip is obtained. Stress intensity factor calculated from the solution can be applied to any crack length and angle. Stress intensity factor generally depends on the ratio of the elastic moduli except for the case of R=Q and ℓ=h. Discontinuity in stress intensity factor as the crack angle ω approaches zero is found, while the energy release rate is shown to be continuous at ω=0. Limiting case of the crack length b approaching zero is also investigated. Energy release rate in this case is enhanced at some ω if the inclined crack exists in the more compliant material.
