Flow stress ratio

Web12.4.1 The Ratio of Draw Stress to Flow Stress In the simplest concept of drawing, a break occurs when the draw stress equals the yield and/or breaking stress of the wire at the die exit. Yielding and breaking are generally associated because of the instability created by the plastic stretching of the wire between dies. WebBasics of Turbulent Flow Whether a flow is laminar or turbulent depends of the relative importance of fluid friction (viscosity) and flow inertia. The ratio of inertial to viscous forces is the Reynolds number. Given the characteristic velocity scale, U, and length scale, L, for a system, the Reynolds ... on the bed stress, ...
