Investigation of Gage-Placement Effects on a Stress Gage Embedded in Grout
The report documents a study conducted on the Gulf Radiation Technology (GRT) piezoelectric stress gage in support of the Diamond Mine Event at the Nevada Test Site (NTS). The gage was first calibrated in oil and then embedded in an NTS grout and tested under conditions of uniaxial strain. The results of these tests indicated a slightly nonlinear output of the gage under hydrostatic loadings and an underregistration of the gage when embedded in the grout. Limited uniaxial strain tests were concurrently conducted on the grout mix. The property information from these tests was used as input to the WESTES finite element code in which the test boundary conditions were simulated to analytically investigate behavior of the grout specimen with and without an embedded inclusion or gage. The calculated results indicated that the contact interface between the gage and the grout had the greatest effect on gage performance. (Author)
