WebDec 7, 2016 · Many types of impact tests have been used to evaluate the notch toughness of metals, plastics, and ceramics. The types of impact tests can be generally classified in terms of loading method (pendulum stroke or drop weight loading) and the type of notched sample (e.g., Charpy V-notch, Charpy U-notch, or Izod). The following descriptions briefly ... WebNotch toughness is a measure of the energy absorbed (impact energy) during the fracture of a specimen (in the presence of a flaw – usually a V-notch) of standard dimensions and geometry when subjected to very rapid (impact) loading. As mentioned previously, a material will likely exhibit a lower level of toughness in the presence of a flaw, such as a notch or …
