Optimization of Substrate Sizes for In Situ Stress Measurement in Electrodeposits Relying on Nonlinear Effects

Coatings, 2023
In situ stress measurements have been widely used in various deposition processes for stress detection. The substrate size can affect the uniformity of curvature across the entire surface, which is a major cause of incorrect stress measurements. However,

Study on Acoustic Emission In-situ Stress Measurement Techniques Based on Plane Stress Condition

Procedia Engineering, 2011
In-situ stress is the key parameter for underground and slope rock engineering design optimization. Hydraulic fracturing method and trepanning stress relieving method are the two main in-situ stress measurement methods for the present, but both of the ...

Methods of in situ Stress Measurement

1997
Compared with other rock mass properties, rock stress is a difficult quantity to measure. As pointed out by Leeman (1959), ‘It is impossible to measure stress directly since, in fact, it is a fictitious quantity. It is only possible to deduce the stresses in a solid body from the results of measurements using some indirect method’.

In Situ Stress Measurements in Austria

1980
In situ stress measurements were made at 6 locations in Austria, which were chosen in such a fashion as to yield information on the neotectonic stress in the country. Because of a strong influence of the Alpine topography, it was necessary to apply finite-element calculations for the interpretation of the field results.

Deep in-situ stress measurements by hydrofracturing

Tectonophysics, 1975
Abstract Hydrofracturing is a recently developed in-situ stress-measuring method. It consists of hydraulically pressurizing a sealed-off interval inside of a borehole until fracture initiates. The fracture is then extended by additional pumping of fluids from the surface.

In‐Situ Stress Measurements in Singapore

Chinese Journal of Geophysics, 2012
AbstractIn the year 2008 and 2009, in‐situ stresses were measured in 18 boreholes by the hydraulic fracturing method to determine the present‐day stress state of the shallow crust in Singapore, which provide key parameters for the design and construction of underground tunnels and data for the study of world stress environments.

In Situ Stress Measurements in Italy

1980
Most of the in situ natural state-of-stress measurements have been carried out in Italy at the sites of large underground hydroelectric powerhouses and at the sites of important mines. The method successfully used was in all cases based on the measurement of the deformations caused by the stress release on the bottom of boreholes.
