Design and manufacturing of the fatigue test machine. Fatigue test is one of the most important tests in the materials science. Since most of the fatigue machines designed and manufactured for this purpose can be adjusted only for amplitude adjustment and count frequency, evaluations are made only based on the number of rupture cycles for fatigue tests.Key Words: Fatigue, failure analysis, fatigue testing machine design against the failure mode Over the years, there have been varied testing equipment and methods developed for fatigue evaluation . The servo – hydraulic machines are currently the fastest and most versatile with features that allow for a wide range of test variations to be .Many engineering machines and mechanical components are subjected to fluctuating stresses, taking place at relatively high frequencies and under these conditions failure is found to occur. This is called fatigue failure. And this led to the invention of a fatigue testing machine. In view of effective design that will not fail accidentally, this research is conceived.
