20150219539 | METHOD OF DETERMINING THE NON-PROPAGATION THRESHOLD OF FATIGUE CRACKS AT HIGH FREQUENCY - A method of determining the non-propagation threshold of fatigue cracks at high frequency, wherein cyclic loading is exerted on at least one testpiece having an elliptical hole in a testpiece zone, the elliptical hole having a notch at one end and the testpiece being held between two rigid masses with two rigid pre-stress plates being arranged on either side of the at least one testpiece and each fastened at its two ends to the two rigid masses, which cyclic loading is at a frequency that is selected as being equal to the resonant frequency of the assembly including the testpiece, the masses, and the stress plates, so as to generate a fatigue crack from the notch, and then once it has been observed that the crack has stopped propagating, the final length of the crack is measured and a chart is used to determine the non-propagation threshold. | 08-06-2015 |
