摘要
This paper presented an original bending fatigue-testing setup for fatigue characterization of composite materials. A three point quasi-static setup was introduced that was capable of applying stress control load in different loading waveforms, frequencies, and stress ratios. This setup was equipped with computerized measuring instruments to evaluate fatigue damage mechanisms. A detailed description of its different parts and working features was given and dynamic analysis was done to verify functional accuracy of the device. Feasibility was validated successfully by conducting experimental fatigue tests.
