... that the FBG system gives a high accuracy (0.04 µ-strain) and temporal resolution (>1s) with pointwise measurements. The bare DBS leg yield good quantitative strain data with poorer strain accuracy (>500 times poorer than FBG) and poorer temporal resolution (factor of >100). The packed DBS leg provide...

.... The results of data analysis showed that it is possible to create a model of frequency buildup behavior. The graph of strain data versus time shows how the heat waves pass through the shale with specific frequencies as it is exposed to the heat load. Additionally, we have calculated Poisson’s ratio...

... results show that strain data from sensors mounted on the rock surface correlate with changes in air temperature within the mine. In order to isolate the mechanical strain signal, we use a least squares linear thermal expansion analysis to fit the temperature and strain data. The least squares analysis...

..., time-dependent deformation is most often observed and characterized by conducting creep-strain experiments [e.g. 12]. However, creep-strain data are not routinely collected or reported in the literature, so it would be useful to have a means for obtaining creep function parameters from whatever data...
