Abstract

Abstract: Fracture is an common type of failure for engineering structures， the stress intensity factor is an key parameter to control the cracked structures. In present work, a method to estimate the stress intensity factor by using the conservation law was proposed for the specialshaped pipes with periodic cracks under mode II loads such as torque.
