Abstract:

This paper shows the effects of fluid pressures to 140 ksi on four different types of SR-4 foil-type strain gages. Linear pressure-strain curves were obtained for these gages mounted on flat surfaces of tungsten, steel and aluminum specimens. The inverse slope of the pressure-strain curves is compared with the compressibility constant 1-2nuE as calculated from experimentally determined values of E and nu. Experimental results show the percent deviation between the constants to be a function of the material, being greatest for tungsten and least for aluminum. Temperature effects, as a function of the rate of applied pressure, are investigated. The types of gage failures encountered along with photomicrographs showing probable causes are presented. Author
