摘要
In the present study we describe an experimental fracture material property test method specific to dynamic fragmentation. A spherical metal sample is subjected to controlled impulsive stress loads by acceleration to a high velocity in a light-gas launcher with subsequent normal impact onto a thin plate. Motion, deformation and fragmentation of the test sample are diagnosed with multiple flash radiography. Strain-to-failure and fragmentation property data for several steels, copper, aluminum, tantalum and titanium are reported. The processes leading to failure and fragmentation have been analyzed with computational methods.
