well as notch configuration and depth can influence the test results. Rolfe and Barsom (1987) developed a correlation between CVN and Fracture Toughness (K Ic) that is given by: Where K Ic is the fracture toughness at slow loading rates (ksi(in) 1/2), σ ys is the 0.2% offset yield strength (ksi), and CVN is the standard Charpy V-Notch impact ...

A fundamental study on the flow past a circular cylinder ...
imechanica.orgFlow patterns generated around a circular cylinder immersed in a uniform flow are shown in Figure 1 (Hughes & Brighton, 1999). In relation to the flow around an object, a combination of a uniform flow with a circular cylinder will be the simplest case. The pattern of this flow varies depending upon the Reynolds number.
