WebSo to check for the modified Goodman line, we say n is equal to 1 divided by our alternating stress divided by our endurance strength, our endurance limit plus our mid-range stress divided by our ultimate strength. WebThe Goodman Diagram is only good for one point on the fatigue curve. The Goodman Diagram will change for different points on the fatigue curve. The amplitude stress line σ a represents the Goodman equation. The diagram may also be called a 'range-of-stress' diagram or a 'modified Goodman range-of-stress' diagram.
