Instrumentation for earth stresses and motions produced by explosions
Ingram, Leo F.
Miscellaneous PaperAbstract: Instrumentation for measurement of earth stresses and motions caused by explosions is described. Emphasis is on field transducers used in the strong shock region beyond the crater and on gages used in blast-simulation devices in the laboratory. Included in the discussion of stress, strain, and motion sensors is a description of a newly developed dynamic soil stress gage and various other current devices applicable in this field. Problems associated with gage installation and placement are discussed. Requirements of the electronic signal conditioning and recording equipment are mentioned. These requirements include frequency response and data processing.
