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 famessec. Data were obtained at fluences that varied between 5 calsq cm elastic response and 20 calsq cm elastic-plastic response.
