Tested materials include: standard aluminum, Eagle Ford shale, Berea sandstone, and Jubaila carbonate. Results reveal: 1) Contact deformation adds non...

... of the joint. In addition, strain gauges are used to measure the slippage on the natural fracture. The tests are carried out on 101.6 mm diameter cylindrical samples of PMMA and shale. The calculated displacement based on the recorded strain clearly shows a jump at the breakdown point, which is accompanied...

... Abstract: Three new methods for identifying axial forces in ground anchor or rock bolt are presented. Unlike in traditional methods that rely on the use of an electronic device, such as strain gauges or load cells, these new methods do not use electronic devices for reading data, but instead...

... of maximal compressive stress. Then the dilatometer is placed to the interval with strain gauge sensors being on the surface. This device is similar to the borehole strain-meter by structure (Fig.1) [6, 7]. However the strain-meters are situated in such way, that they allow to measure circular deformations...

.... Axial deformations were measured by means of strain gauges and also three LVDTs arrayed 120 degrees apart from each other (Fig. 7). Circumferential deformation was captured by means of strain gauges and an extensometer. The samples were monitored using six AE transducers while loading. The specimens...
