RECORDING OF HIGH-SPEED PROCESSES IN IMPACT DESTRUCTION OF A CONTAINER FILLED WITH A FLUID

An experimental procedure has been developed to record phenomena in impact destruction of a container with a fl uid. The phenomena were recorded using x-ray pulse devices and a high-speed fi lming technique. The propagation of compression waves in the fl uid was registered using bubble-markers in the form of air curtains in the fl uid mass. The pressure in the compression wave was measured by a gallium arsenide crystal-based sensor. An investigation has been made into the characteristics of the phenomena occurring during the destruction of a container with a fl uid by a high-speed striker. We have established the dependences of cavity development in the fl uid, the striker motion law, the time dependence of pressure, and the pressure attenuation in the fl uid. The obtained dependences make it possible to establish objective physical data on phenomena in impact-stressed containers and to solve the issue of strength of a container with a fl uid.
