This report documents the investigation of correlations between Charpy V-notch impact energy and fracture toughness. Three distinct types of correlations were examined: (1) the Rolfe-Novak-Barsom upper-shelf correlation, (2) the hyperbolic tangent (tanh) correlation, and (3) the J-..delta..a correlation. The Rolfe-Novak-Barsom correlation is a straight line relationship between functions of the Charpy energy and the static initiation toughness, while the tanh correlation relates functions of the Charpy energy and either the static or the dynamic toughness through the use of statistically determined curve fits based on the tanh curve. The J-..delta..a correlation represents power law estimates of resistance curves in the upper-shelf temperature range.
