A simple homogeneous rock, Arkansas novaculite, was chosen for dynamic tensile failure studies. Experimental techniques for performing dynamic tensile tests on rocks were developed and used to provide meaningful measurements of dynamic tensile strength. A way to eliminate the occurrence of undesirable radial cracking of the specimen during testing was found specimen recovery and fracture analysis methods were implemented. Novaculite specimens were characterized with respect to static and dynamic fracture strength, fracture toughness, defect and microstructure, and other properties and parameters pertinent to the fracture behavior.
