| 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. |
