Mechanical components are generally expected to be damaged by fatigue processes along their lifetime. Since the maximum allowable stress value is reached, some irrecoverable and cumulative damage appears in materials. That process is related with the nucleation of superficial or volumetric discontinuities (micro-cracks or micro-cavities) and begins when any localized stress is greater than the material yield stress. For components where fatigue damages are determinative, the existence of a reliable way to measure and evaluate them is highly desirable. Quantitative evaluation of fatigue damage in materials is a complex task and involves their macroscopic and microscopic properties as well as other physical ones. In this work, high cycle fatigue tests were performed at laboratory in aluminum alloy 2024-T3 specimens and the changes verified in their electrical resistivity were accurately measured. Curves, correlating the number of loading cycles with the electrical resistance changes of a section of specimens were plotted and significant changes were observed. It is well known that magnetic permeability and resistivity changes in materials, associated with the test frequency and the geometric aspects of the tested object are the main parameters considered for the application eddy current as a nondestructive testing method. So, based on the presented results, the development of an eddy current test arrangement for cumulative fatigue damage evaluation in aluminum alloy 2024-T3 is suggested.
