A technique has been developed for impulsive loading of rings. It consists of spalling a thin, curved flyer plate from the inner surface of a curved buffer plate by the pressure pulse from sheet explosive on an outer surface. The flyer plate travels radially inward a short distance before impacting a test ring. A passive impulse gage has been developed for use in underground nuclear tests. It consists of a piston and restraining spring and incorporates a recording device for separating the piston deflection due to the impulsive load and the deflection due to later arriving extraneous loads.
