The approximate solution of penny-shaped cracks periodically distributed in infinite elastic body

  • Zhou Jianping
  • Lu Yinchu


The penny-shaped cracks periodically distributed in infinite elastic body are studied. The problem 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.

Key Words

stress intensity factor dual equation crack interaction factor
