Abstract
The prediction technique developed in this effort defines cavity wall loading as a function of scaled distance. The cavity wall pressure, which is strongly influenced by the stagnation of the detonation products, was used to determine peak radial stress in the free-field. A material strength parameter was identified to define the appropriate range to the elastic limit boundary as developed in the model. Beyond the elastic limit the procedure provides for calculation of peak radial particle velocities from elastic plane-wave theory with appropriate attenuation.
