Summary Report on the Development of Stress and Deformation Measurement Techniques

摘要

The literature was reviewed to determine which instruments or techniques have the potential for measuring stress, displacement and elastic modulus in a nuclear waste repository environment. Four instrument types were determined to have this potential: the USBM gage and the CSIRO gage for stress determination, and the rod extensometer and the laser interferometer for displacement measurements. Existing modulus measuring instruments were not considered as reliable as the other instruments evaluated. Existing deficiencies in these instruments have been determined, and possible solutions to improve the instruments have been investigated. 24 references, 32 figures, 7 tables. (ERA citation 08:004393)
