STUDY ON THE INITIAL DISCONTINUITY STATE OF 2024-T3 ALUMINUM ALLOY
2024T3铝合金初始不连续状态的研究

The concept initial discontinuity state(IDS) was developed just several years ago in an attempt to describe the as-manufactured or as-produced state of material.In this paper,a number of IDS values were determined for several smooth specimens of 2024-T3 aluminum alloy.A crack growth analysis software AFGROW was used to develop the IDS.The results indicate that the calculated IDS values scatter widely.A statistical analysis shows that the distribution of the calculated IDS values fit well with Weibull distribution.
