摘要：
The penny-shaped cracks periodically distributed in infinite elastic body are studied. The prob-lem is approximately simplified to that of a single crack embedded in finite length cylinder and the stressintensity factor is obtained by solving a Fredholm integral equation. Numerical results are given and the effectsof crack interaction on the stress intensity factor are discussed.
