| Abstrakt: | This paper shows the limits in using the Cranz-Schardin high speed camera for photographing catastrophic fracture in materials with strong photoelastic constants. There is a maximum permissible distance between the sample and the observation plane if one wishes to use the elastic and elastic-plastic fracture theories. We develop a shadow method in which successive pictures of the fracture are superimposed on a photographic plate set near the sample. The results allow an accurate quantitative measurement of either the fracture prppagation or the energy of fracture. |
