| Abstract Scope |
The strength distribution of of ZerodurŪ, as machined and etched, is investigated and determined to be best represented by a normal distribution with large variance but without scale effects. The appearance of a 3-parameter Weibull distribution results from mixing of components of variation. Although a 3-parameter Weibull distribution might be reasonably used, the size effect is missing, and the fixity of the threshold is questionable. Thus, a classical design approach might be used for structural design with this flaw population. |
