Download or read book Influence of Rock Anisotropy and Time-Dependent Deformation on the Stress-Relief and High-Modulus Inclusion Techniques of In Situ Stress Determination written by D. S. Berry and published by . This book was released on 1966 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two of the most popular techniques used in the determination of in situ rock stresses are the stress-relief and high-modulus inclusion methods. Deformations and strains observed in the measuring instruments are usually interpreted on the assumption that the rock behaves as a homogeneous, isotropic, linearly elastic medium, a situation which is not even approximately correct in some practical cases.
