RESEARCH STUDIES ON FREE FIELD INSTRUMENTATION
Abstract
This paper is the final report on a free field stress gage currently under development. The gage was tested under static and dynamic conditions to over 1,000 psi in a pressure tank especially designed and fabricated for this purpose. Present test results indicate that the gage reads within 10% of the free field stress up to somewhat beyond 200 psi. It is believed that future gages, developed along the same lines, will accurately measure free field stresses up to 1,000 psi. An important side result was the design and fabrication of a dynamic pressure tank used in gage development and evaluation. The tank is capable of producing static and dynamic pressures of over 1,000 psi. At present dynamic pressure rise times (time for pressure to reach 63% of its final value) range from 10 to 40 milliseconds. (Author)
