Rotating-bending fatigue testing has become a common test setup for the structural fatigue evaluation of Nitinol wires (Tobushi et al., 1998). . Also uncoated substrate specimen was considered. Tests were carried out on cantilever type rotary bending machine for loads of 100, 150, 200 N. Load ratio considered is 1. .A method for estimating the crack growth rate in steel during rotating‒bending fatigue testing is presented. Constant deflection tests were conducted in which the initial load remained constant prior to crack nucleation, when it decreased as the crack grew. In the proposed approach, steel samples were sharp-notched to produce a characteristic circular fracture upon loading and the . A large-scale fatigue testing machine based on the rotating beam method in a four-point bending configuration was designed and built. With the device, high-strength metal specimens with a 32-mm gauge diameter and a 100-mm gauge length can be tested at a cyclic frequency of up to 48 Hz. In this work, particular attention was paid to evaluating the spatial .Cantilever beam type of rotating-bending fatigue testing machine (from Collins, J.A. (1993), Failure of Materials in Mechanical Design, Wiley). Much of the available fatigue data is based on the rotating-bending test, which provides a completely reversed loading. A disadvantage of the rotating-bending test is the difficulty with applying a non .
Rotating Beam Fatigue and Axial Fatigue Test Methods. The main difference between the two test methods is that axial fatigue testing applies uniform stress throughout the cross-section of the specimen under test, whereas rotating beam fatigue testing creates an applied stress that increases linearly from 0 at the neutral axis to a maximum stress value at the specimen surface. The piping component tests which are generally performed to develop fatigue design S–N curves and, subsequently, to determine the stress intensification factors (SIFs) are rotating bending, four-point bending, and cantilever bending tests.Schematics of their test set-ups are shown in Fig. 1.In a rotating bending test, the pipe specimen continuously rotates .
