Abstract
The effects of precracking load on critical stress intensity factor are studied. A plane stress model of elastic/plastic stress distribution which has strain hardening effects included is used. The effects of residual stresses and strain hardening due to fatigue load are calculated by choosing plastic zone size as fracture criterion. And experimental results are obtained to prove the reliability of theoretical calculations. The results show that the influence of fatigue load can be estimated directly by a computer program.
