Study on the Initial Discontinuity State Distribution of LY12CZ Aluminum Alloy

Abstract:

Article Preview

The initial discontinuity state (IDS) concept was developed just several years ago in an attempt to describe the as-manufactured or as-produced state of material. As a geometric and material characteristic, IDS is the major parameter of holistic life assessment methodology which establishes the initial analysis condition. In this paper, a number of IDS values were determined for several types of smooth specimens. A crack growth analysis software was used to develop the IDS. The results obtained 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.
