Fatigue Testing
Fatigue is the progressive, localized, permanent structural change that occurs in materials subjected to fluctuating stresses and strains that may result in cracks or fracture after a sufficient number of fluctuations. Fatigue fractures are caused by the simultaneous action of cyclic stress, tensile stress and plastic strain. If any one of these three is not present, fatigue cracking will not i...
متن کاملRedesigning axial-axial (biaxial) cruciform specimens for very high cycle fatigue ultrasonic testing machines
The necessity to increase performances in terms of lifetime and security in mechanical components or structures is the motivation for intense research in fatigue. Applications range from aeronautics to medical devices. With the development of new materials, there is no longer a fatigue limit in the classical sense, where it was accepted that the fatigue limit is the stress level such that there...
متن کاملBiaxial testing of nanoscale films on compliant substrates: Fatigue and fracture
Two problems of technological importance for microelectromechanical systems ~MEMS! and microelectronics industry are addressed: fatigue of thin films and nanoscale film cracking. A device is described that can ~1! conduct biaxial fatigue tests on thin films and ~2! be utilized to study fracture patterns in nanoscale coatings under biaxial stress state. Thin-film specimens, in the form of circul...
متن کاملPid Tuning for Multi-channel Structural Fatigue Testing System
A proportion-integration-differentiation (PID) controller is a generic control loop feedback mechanism widely used in multi-channel aircraft structural fatigue test. The PID parameter is obtained by test setup method in which PID is tuned after the test setup is actually performed, so that the tuning period becomes overlong. And the dynamic characteristic of mechanical and hydraulic equipment i...
متن کاملRatcheting-Fatigue Failure of Pressurized Elbows made of Carbon Steel
Ratcheting-fatigue investigations have been carried out to understand the ratcheting-fatigue failure of carbon manganese steel (conforming to ASME specification of SA-333 Gr.6). Experiments have been conducted on pressurized pipe-elbow assembly subjected to reversible cyclic bending, to assess the failure mechanics owing to ratcheting-fatigue synergy. These studies are required to evaluate the ...
