Stress-states in situ

1989
The undisturbed in situ rock before an excavation is already under a certain stress. This stress-state is due to a variety of causes: gravity, stresses due to tectonic motions, the strata orientation, the creep and relaxation produced during geological periods, possible local unloading due to a relatively fast erosion, thermal contractions, etc.

In-Situ and Ex-Situ Measurement of Stresses in Environmental Barrier Coatings

Volume 2: Ceramics and Ceramic Composites; Coal, Biomass, Hydrogen, and Alternative Fuels
Abstract Ceramic Matrix Composites (CMCs) offer a step improvement in temperature capability over the current best high temperature super alloys for gas turbine applications. Silicon Carbide (SiC) based CMCs react with water vapor at temperature and therefore need an Environmental Barrier Coating (EBC) for protection against the water ...

In-Situ Rock Stress

2006
Understanding the stress state in the earth's crust is crucial for engineers working in rock, particularly with regard to underground construction. Experience shows that an adequately high horizontal in-situ stress has a positive effect in stabilizing large span rock caverns close to the ground surface.

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.

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 Gauge Calibration.

1977
Abstract : The accuracy of 'in situ' stress measurements is dependent upon the presence of strain within the active gauge element. In gauge records of dynamic stress fields, the onset of strain response of the gauge is not able to be defined. Development of a gauge that responds only to the applied pressure, independent of the strain field, is usable ...
