IMPACT ENERGY AND NOTCH SENSITIVITY OF CERAMIC MATERIALS.

Abstract

The notched and unnotched impact energies of alumina, boron carbide, and silicon carbide were studied by the drop weight testing technique. The notch sensitivity ratio is defined as the ratio of unnotched to notched impact energy. It is shown that the notch sensitivy ratio varies from about 1.5 for a ductile material such as Ti-6Al-6V-2Sn to about 18.0 for the extremely brittle silicon carbide. The drop weight testing technique is better suited to determining impact energies of very brittle materials than the more conventional Charpy or Izod methods. (Author)
