文摘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 stress intensity factor is obtained by solving a Fredholm integral equation. Numerical results are given and the effects of crack interaction on the stress intensity factor are discussed.
