WebThe critical flaw size in torsion is several times larger than the flaw critical size in tension. The damage maps in Figures 17–19 showed that at long lives it is much easier to nucleate cracks in torsion than in tension. As a result smaller flaws are not as damaging in torsion because other cracks will naturally nucleate in the material. WebBecause of the conservative nature of ASIP, it is assumed that all critical airframe components have an initial flaw size to account for any damages that could have occurred during the manufacturing and maintenance processes. Generally, ASIP assumes a 0.05-inch flaw because it is equivalent to the minimum detectable flaw size of a typical ...
