Technique presented yields good correlation to field life with significant reduction in testing time; simple load control programs used are within capabilities of most fatigue test machines, and servo-hydraulic test equipment; two new concepts, test acceleration by use of "mixed cycle" S-N curve and technique to simulate multiple modes of loading, are combined with known simulation methods to form overall technique; application of technique to life testing of automotive components at Ford Motor Co is shown and correlation to field life discussed; test program is developed for chassis frame, and two applications of technique are described.
