Holographic in situ stress measurements [PDF]
Geophysical Journal International, 1986 A new instrument for measuring the in situ level of stress in boreholes has been developed. The instrument operates on the principle of locally relieving the stresses acting on a rock mass by drilling a small hole into the borehole surface and recording the resultant displacement field by holographic interferometry.

Measuring forces and stresses in situ in living tissues [PDF]
Development, 2016 Development, homeostasis and regeneration of tissues result from a complex combination of genetics and mechanics, and progresses in the former have been quicker than in the latter. Measurements of in situ forces and stresses appear to be increasingly important to delineate the role of mechanics in development. We review here several emerging techniques:

A Bayesian Approach for In-Situ Stress Prediction and Uncertainty Quantification for Subsurface Engineering [PDF]
Rock Mechanics and Rock Engineering, 2021 Many subsurface engineering applications require accurate knowledge of the in-situ state of stress for their safe design and operation. Existing methods to meet this need primarily include field measurements for estimating one or more of the principal ...

Thermally Induced Rock Stress Increment And Rock Reinforcement Response [PDF]
, 2016 The thermal heating caused by the deposition of spent nuclear fuel containers increases the in situ rock stress during disposal time. The thermal stress increase was modelled using thermo-mechanical modelling.
