WebThe energy absorption, or toughness, of a material is measured by various techniques and two most commonly used methods are: Izod and Charpy Test. The two methods are based on common principle of applying the load at high rate and measuring the amount of energy absorbed (Kg/m or Joule) in breaking the sample due to impact. WebMar 16, 2005 · Impact energy is a measure of the work done to fracture a test specimen. When the striker impacts the specimen, the specimen will absorb energy until it yields. At this point, the specimen will begin to …
