The development of conical stress forms by explosive charges

Author

Abstract

"Usually stresses generated by explosive charges during blasting are considered to propagate through materials in a spherical manner. Although conical stress waves had been suggested by a few investigators they have never been clearly defined or studied in the laboratory.

An experimental technique using models was developed to produce conical stress waves from an explosive. Several materials with different properties were selected as models for the purpose of determining whether or not conical waves could be generated in all materials.

This investigation showed that conical stress waves do exist under certain conditions, which would closely approximate those present for much of field blasting. The angle of the developed stress cone was found to directly affect the shape of craters produced. In addition, the minimum angle of incidence for the stresses impinging on accoustical interfaces was defined by that angle"--Abstract, page ii.
