Abstract
In order to develop a precise relationship between Charpy V-notch impact energy and mechanical properties, Charpy impact tests were carried out for a variety of structural material. A simplified correspondence between the dynamic and static tests has been a subject of practical importance. A number of widely different materials such as low, medium, high strength steels, carbon steels, spheroidal graphite cast irons and aluminum alloys, which are generally used as structural engineering components, were employed in this study. As a result, Charpy absorbed energy in the upper shelf region was well correlated with local fracture strain of tensile specimens as well as reduction of area of the materials. The useful correlations were thus established to estimate upper shelf energy directly from uniaxial tensile mechanical properties in a simple manner.
