IN SITU MEASUREMENT OF WOOD STRESS DURING DRYING PROCESS

Sensors and Microsystems, 2004
Innovative in situ measurement of internal stress of wood during the drying process is presented. In order to quantify the internal stress and subsequent strain generated in wood during the process(1,2), different indirect and semi-direct techniques can be adopted such as the asymmetrical drying test, and other standard destructive tests(3), these semi-

In situ stress measurements in anisotropic rock

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1984
Abstract The purpose of this paper is to discuss how to account for rock anisotropy when measuring in situ stresses by overcoring with instrumented devices such as the CSIRO hollow inclusion cell or the U.S. Bureau of Mines (USBM) gauge. The rock is described as an isotropic, a transversely isotropic or an orthotropic material. The computation of in

Holographic In-Situ Stress Measurement in Geophysics

1983
A new and still experimental method for measuring the absolute in-situ stress field in crustal rocks offers several advantages compared to existing in-situ stress measurement techniques. It employs optical holography to record strain-relief displacements in a borehole environment. We call the prototype instrument the holographic stressmeter.
