In many works, it was tacitly assumed that Hill's [11] suggestion of having the orthotropic directions aligned with the principal plastic stretch directions is valid, and this is indeed the case when loading maintains fixed principal stress directions from the onset of plastic deformation.
The arch is the path of the major principal stress, and the direction perpendicular to direction of the plane which the minor principal stress acts.
The geometric model was meshed in tetrahedral finite elements, C3D8 (154742 elements) and based on FEM simulation, one determined the Maximum Principal Stress (Fig.
In the case of isothermal flow, a profile of principal stress difference from the surface to the core shows a V-shape, so molecular orientation is directly related to fountain flow (9).
Because the reservoir extends normal to the minimum principal stress direction in theory, it was expected that hydraulic fracturing creates the reservoir extending horizontally.
Many result quantities from finite element analysis contain directionality as well as value, and, in fact, there is an inherent directionality in most analysis data such as principal stress and deformation.
However, the experimental results show that the intermediate principal stress is the important characteristic of rock and soil mass.
in the non-cracked component the maximum principal stress reaches at a point the material strength [sigma]([I.
The direction of the tensile opening calculated by the moment tensor evaluation coincides very well with the direction of the minimum principal stress.
Earlier in his career, he was a principal stress engineer at Sperry Gyroscope from 1979 to 1981.
