| 520 | 3 |a"A method of analysis is developed to compute the stress distribution resulting from detonation of a contained spherical charge in an elastic medium in the vicinity of a free face. This analysis uses the dynamic elastic properties of the medium, and the direct dilatational displacement and particle velocity wave shapes produced by the explosive, as a function of distance. Principal stresses at a point, as a function of time, are computed by superposition of the stress components due to the direct dilatational wave and the reflected dilatational and shear waves, using plane wave reflection theory. A computer program has been written to perform this analysis"--Abstract, page i. |
