Studies of Reactor Containment. Task No. 6 on Explosives Test Evaluation of Blast Shields for Nuclear Reactors. Report No. 1. A Technique for the Observation and Measurement of the Behavior of Porous Materials When Rapidly Compressed

PDF Version Also Available for Download.

Description

The technique described may be used to obtain data regarding the behavior of porous media when they are rapidly compressed. Data which can be obtained include relationships between stress and strain under dynamic conditions, coefficients of restitution, compression wave velocities, decay rates and wave form modifications. Although there is still room for improvement and refinement, the present technique can be used to produce data needed by, and not previously available to, designers of blast shields and similar structures. The data presented herein are preliminary, included mainly to illustrate the usefulness of the technique. It may be noted, however, that they ... continued below

Description

The technique described may be used to obtain data regarding the behavior of porous media when they are rapidly compressed. Data which can be obtained include relationships between stress and strain under dynamic conditions, coefficients of restitution, compression wave velocities, decay rates and wave form modifications. Although there is still room for improvement and refinement, the present technique can be used to produce data needed by, and not previously available to, designers of blast shields and similar structures. The data presented herein are preliminary, included mainly to illustrate the usefulness of the technique. It may be noted, however, that they leave little room for doubt regarding the value of porous materials in the absorption of shock energy. The coefficients of restitution are velocity ratios. Since the kinetic energy varies as the square of the velocity, between 90 per cent and 96 per cent of the initial kinetic energy was absorbed in the cases cited. (auth)
