Thickness charpy energy tests
Web1 Oct 2015 · The curves of Charpy impact energy Ak versus plate thickness for steel plate at 20 °C are given in Fig. 7a. It can be seen that as the plate thickness increases from 60 to 165 mm, the transverse and through-thickness Ak values reduce by almost 11% and 80%, respectively. Curves for the 60 mm plate are shown in Fig. 7b.
