  • Improvement of experimental device for high cycle fatigue tests of copper alloy strips and characterizing fatigue properties

説明

<p>In this research, we improved on a fatigue test machine based on the published fatigue test method for copper alloy strips, examining and modifying each unstable element, shortening the test time and performing stable 108 fatigue cycle tests. Then, the strip fatigue test was conducted using the improved fatigue test machine. As a result, it was confirmed that the fatigue cycle was improved in the transverse direction specimen of the copper alloy strip, and the cause was examined by observing the fracture surface. The location of the crack was identified, and it was confirmed that it was consistent with the FEM analysis.</p>
