History of constant life diagrams
- Wright Lab. Materials Directorate, Wright-Patterson AFB, OH (United States)
A historical review of the early development of constant life diagrams (variously referred to as Goodman, Smith, Haigh, etc. diagrams) is presented. It is shown that neither Gerber nor Goodman published the first constant life diagram. Goodman never drew what is now called the Goodman diagram and the so-called Goodman law was in general engineering use before Goodman`s book first appeared. Johnson derived an equation that is equivalent to the so-called Goodman law, published it two years before Goodman`s book appeared, and pointed out that it was consistent with an equation in common engineering use. The first books on fatigue of metals introduced citation inaccuracies, which were propagated by subsequent authors. 40 refs., 5 figs.
