Stress Intensity Factor for Special-Shaped Pipes with Periodic Cracks
摘要
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.关键词
