Bower and Ortiz's finite perturbation method is used to analyze the gradual growth of penny-shaped and half-planar cracks between barriers whose fracture toughness is greater than that of the fracture zone. The breakthrough of a crack front into barriers when the stress intensity factor at some points along the interfaces exceeds the fracture toughness of the barriers is considered and the associated changes in the distribution of stress intensity factor and the pressure on the crack faces is calculated. The results indicate that under constant pressure on crack faces, a bounded crack expands indefinitely while a semi-infinite crack would grow stably.
