A Literature Review to Assess the Reliability of the. The Charpy impact test is a dynamic test in which a test piece U-notched or V-notched in the middle and supported at each end, is broken by a single blow of a freely swinging pendulum (Fig.1). The energy absorbed is measured. This absorbed energy is a measure of the impact strength of material., T. A. Siewert and C. N.
