...R. D. Blevins Fatigue is produced by the sum of randomly phased sine waves. Fatigue damage during this non-Gaussian, finite random process is a function of the noise bandwidth, the fatigue slope, mean stress, and the rms stress. Methods are developed for predicting the cycles to failure. Comparison...

... for the displacement of the vehicle and beam are determined for harmonically varying surface irregularities. Next, the surface irregularities are modeled as a random process. The variance response of the mass of the vehicle as well as the displacement variance of the beam under the oscillator are determined in terms...

...G. Petrucci; M. Di Paola; B.
