*Edit***Goodman Diagram**. The alternating stress is plotted on one axis and the mean stress on the other. Goodman diagram ≈ endurance limit as a function of mean stress.

Goodman diagram is used to analysis the static and fatigue stresses. The Modified Goodman Diagram is the red line and is the Goodman line truncated by the Yield line. The rotor blades shall be of the tapered/twisted, free vortex, reaetion design A Goodman Diagram shall be provided for tlie highest stressed loeation of the rotor blade at the normal.

### How can one extend the Haigh diagram for compressive stresses?

Goodman diagram is the basis of analyzing the endurance (fatigue) life of ferrous. material.

The most common format used in. How to create a Haigh diagram (goodman diagram)? To better understand this concept one should know about the fatigue stress… to explain it furthur ill explain this topic with some basic.
