Web3 Turbulence Intensity: urms/u (5) The subscript ‘rms’ stands for root-mean-square. You should recognize the definition of urms given in (4) as the standard deviation of the set of “random” velocity fluctuations, u′i. Similar definitions apply to the lateral and vertical velocities, v(t) and w(t). WebMay 11, 2011 · Yield stress (Y) indicates the start of plastic deformation. Y is determined approximately by drawing a parallel line to the linear elastic region of the flow stress curve from 0.2 percent engineering strain. The intersection of this parallel line with the flow stress curve gives the value of Y. Ultimate tensile strength (UTS) is the maximum ...
