A fiber bridged crack near a free surface in ceramic matrix composites is analysed. The crack is modeled as a continuous distribution of dislocations. The solution of a single dislocation in an elastically anisotropic half plane is derived using complex variable analysis. This solution, combined wit
The effect of a free surface on fatigue crack behaviour is discussed in the paper and generalized stress intensity factor methodology is used for a reliable estimation of the fatigue crack propagation rate in the area close to a free surface, where the effect of vertex singularity is important. It i
A perturbation mapping method and a computational procedure are presented for evaluating the sensitivity coecients of the stress intensity factors for three-dimensional planar cracks near a free surface. The boundary integral equations for evaluating the sensitivity coecient are solved by using the
A B S T R A C T Our theory of fatigue crack growth, which is based on the Bilby, Cottrell, and Swinden crack theory, is modified to take into account work hardening at fatigue crack tips. Iii this analysis stress rather than cumulative displacement or cumulative damage is the quantity whose critical
