WebSep 30, 2015 · Shaft Design for Stress Now we can take the acquired von Mises stresses and use these values in any of the known fatigue failure criteria to evaluate the factor of safety n or, for design purposes, the diameter d. Reminder of the fatigue failure criteria: DE-Goodman DE-Gerber DE-ASME Elliptic DE-Soderberg 18. WebJan 21, 2024 · The Goodman theory states that for all the in-between cases you draw lines from A to B and from A to B' to define the endurance limits in the presence of non-zero average stress (midrange stress). This hypothesis is supported from testing (in some other page in Shigley book) and from the elastic theory of solids.
