DESIGN AND FABRICATION OF DUAL SPECIMEN ROTATING BENDING FATIGUE TESTING MACHINE

Abstract: Testing different materials for their fatigue behaviour has been a major requirement before consider the material for use in any environment with continuous fluctuating load. There has been major evolution in the design of fatigue testing machines for over a century now. But the concept that was lacking in the testing industry was that of a fatigue testing machine that can simultaneously test the fatigue strength of two specimen. In this paper, the attempt to bring this concept to life has been explained. The design of this fatigue testing machine is different from other fatigue testing machines because it can hold two specimens at any given time.
