Goodman FAD

Goodman FAD, Goodman Fatigue Analysis Diagram, is prepared for engineers and students to solve fatigue strength problems easily.

Fatigue, or metal fatigue, is the failure of a component as a result of cyclic stress. When the component is to be designed for infinite life, the endurance limit becomes the criteria of failure. Goodman FAD calculations can be carried with either “residual stress method” or “nominal mean stress method”. 

Goodman Diagram constructed automatically once all parameter are entered. Critical points are calculated and given on diagram and judgement belongs to the user based on these points.

Users can save and load basic diagram parameters.
