Dynamic fragmentation of brittle materials using the torsional Kolsky bar

Conference ·
OSTI ID:5335776
The results of a study of the dynamic loading and subsequent fragmentation of a wide variety of brittle materials using a torsional Kolsky bar apparatus are presented. In the experiments, solid cylinders of various materials were loaded in torsion at shear strain rates in the range 10/sup 2/ to 10/sup 3/s/sup -1/. The energy required to fragment the specimen was determined for each test. In addition, the fragments resulting from each test were collected and analyzed by various techniques to determine their mass and size distributions. The results of our tests indicate a correlation between fragment distribution parameters and material properties, which is in agreement with an energy based analysis of fragmentation.
