Dynamic Fracture Experiments using High-Energy Pulsed Electron Beams
Abstract
The report describes the results of an experimental effort in which high-energy pulsed electron beams were used to study dynamic fracture induced by rapid in-depth heating. The work was performed under the metals portion of the PREDIX program; the materials studied were 6061-T6 aluminum, alpha titanium and OFHC copper. Spallation thresholds for these materials are presented in terms of the absorbed energy required to cause a specified amount of damage as a function of the tensile pulse duration. Differences in the loading paths resulting from plate impact on the one hand and rapid in-depth heating on the other hand are also described.
