| Abstract: | Crack length measurement technique,which used for aeronautical materials under corrosive environment,has been studied in this paper.The Middle-Tension specimen and the corrosive gas cyclic apparatus have been designed and made fitted for automatic measurement using compliance method.The obtained compliance coefficients are proved to be correct by amounts of experimental data in comparison with eye-measurement method.On the basis of this,an automatic measurement technique of fatigue crack length in fatigue crack growth rate test under corrosive environment is established. |
