Keywords : Fatigue Failure, Fatigue Stress, S-N Curve, Endurance Limit, Fatigue Testing, fatigue load. I. INTRODUCTION Fatigue is the process of progressive permanent A. Fatigue Failure structural change occurring in a material which is A fatigue is a failure of material or machine due to the subjected to conditions that produce fluctuating . Fretting fatigue is a phenomenon which occurs when two parts are contacted to each other and one of those parts or both are subjected to cyclic load. Fretting decreases fatigue life of materials drastically by half or even more. Therefore, investigation of fretting fatigue life of materials is an important subject. Fretting fatigue tests are usually performed using universal .Fatigue testing machine is used to determine the fatigue life or fatigue strength of a material. An overlook to the broken parts in most of the scrap will show that almost all failures occur at stresses below the yield strength of . Design and Characterization of a Fatigue .

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.The data used to create these generation of testing machines called ultrasonic fatigue diagrams is acquired in the laboratory by performing test machines working at 20 kHz, reaching 10e9 cycles cyclic tests until the rupture. The classic fatigue test in fourteen hours [5].A closed loop servo-hydraulic structural fatigue testing machine was developed. It can apply fatigue loads on actual engineering parts or components for their fatigue strength evaluation. The testing machine consists of a structural bending load frame, a structural torsion load frame, a hydraulic system, and a control system. Stress analysis and design for the crosshead, .
