The pendulum will hit right above this to break the material. You’ll want to have a vertex that sits at the midpoint of the length of the test material. Then, add the test material to the pendulum testing apparatus, at the bottom where the pendulum will swing and make contact. Secure it with the vise.
Abstract. This paper is focused on the approximation of absorbed Charpy impact energy-temperature curves (KV-T) and the management of sub-size test piece results in Charpy pendulum impact tests. Both subjects are frequently underestimated but may have a strong impact on the assessment of product quality and structural integrity. The status of related test .The Charpy impact test was invented in 1900 by Georges Augustin Albert Charpy (1865–1945), and it is regarded as one of the most commonly used test to evaluate the relative toughness of a material in a fast and economic way.
