Aluminum Ring Thermostructural Response Study
Abstract
The response of aluminum rings subjected to sudden radiation heating was experimentally investigated using pulsed electron beams. The DNA OWL II generator, operating at a nominal mean voltage of 1.0 MeV, provided the radiation environment. Transport of the electron beam from the diode to the target was achieved using a longitudinal magnetic field. The aluminum rings were 8 inches in diameter, 2-inches wide, and 0.12 inch thick. The rings were rigidly clamped over a 10 degree segment opposite from the irradiated side. Circumferential strain data were obtained on the inner surface of the rings at 0, + or - 45, 90, 135, and 170 deg with respect to the axis of the electron beam. Transverse strain data were also obtained at 0 deg. Quartz gauge stress measurements were performed on flat aluminum specimens simultaneously with the ring experiments. The response was also observed with fast motion pictures (4000 fames/sec). Data were obtained at fluences that varied between 5 cal/sq cm (elastic response) and 20 cal/sq cm (elastic-plastic response).
