Abstract

The effects of anvil configurations on the absorbed energy were quantified using Japanese V-notch reference test specimens at three energy levels (30 J, 100 J, and 160 J). All tests were performed on a 500 J C-type machine with a 2 mm radius striking bit. The test temperature was O°C. The effects of five critical parameters of anvils and supports were analyzed with an orthogonal array L¹⁸. These effects were finally expressed as a formula of the uncertainty propagation. Furthermore, the difference of absorbed energy with different tapers of anvils was studied.
