Fluctuating stress examples

WebThe velocity profiles, RMS fluctuating velocity, and Reynolds stress distributions were obtained for different values of nozzle-to-plate distances e = 10 mm, 20 mm, and 30 mm. The mean axial velocity profiles obtained at low NPRs had maximum values along the jet centerline, while those at high NPRs showed the maximum velocity along the nozzle ... Webfluctuating stress of a constant amplitude. A point can be plotted on a graph with the number of cycles to failure (N) as abscissa and the constant amplitude stress (S) as ordinate. Stress range is defined as the algebraic difference between the two extremes of a stress cycle so the constant amplitude fluctuating stress is a constant stress range.
