“…The nine pairs of strain gages may be connected in a number of ways, depending on the specific use of the instrument. Because of the use of thinner material, the sensitivity is greater than for the diaphragm equipped with four active gages that was discussed in Reference [25], Only exploratory studies in an open channel have been made thus far. Therefore I do not know the full capability of the unit in connection with water modeling of combustor systems.…”

Many problems are inherent in measuring stresses in granular materials such as soils. The presence of an inclusion such as a gage disrupts the stress field, causing either stress concentration or stress relief depending on whether the inclusion is more or less stiff than the medium. This phenomenon can seriously affect gage registration. Inertial effects must also be taken into consideration in designing a gage for dynamic measurements. This paper describes the work of the Waterways Experiment Station during the past 2 1/2 years in developing a free-field soil stress gage to minimize these problems. Two different gage sizes were developed. Both sizes use piezoresistive strain gages bonded to stiff diaphragms as sensing elements. Fluid calibrations for the gages are linear to at least 500 psi. Dynamic rise times are approximately 6 μsec. Results of laboratory calibrations in dry sand, and of field measurements during a 500-ton TNT test are presented.
