For example, one would expect the orientation of principal stresses to be affected by topography in the shallow subsurface. Alternatively, as salt bodies at depth could introduce boundaries with near-zero shear strength at an arbitrary orientation, their presence would result in one principal stresses...
Environmental Thermal Cycle Analysis and Testing of Elastomeric Mounted Objective Lens Cell for Head-Up Display System The paper presents the determination of principal stresses, strains and shear stresses due to thermal cycle load experimentally as well as using Finite Ele...

The reason I ask is that by removing material 'in front of' the crack (a series of decreasing circles, the axis along the line of principal stress), the stress concentration at the crack tip can be reduced dramatically. Not that that is what we approved for the particular problem above ...
The residual stresses present in nickel oxide scales formed on the alloys containing the additions are significantly higher than those in the nickel oxide scale formed on pure nickel. It is proposed that the principal cause of this increase in stress is associated with oxide grain refinement due ...
The relations, which are needed for converting initial experimental data into stress values of interest, are presented for thin-walled plane structures. Required input data are obtained by simultaneous measurements of probe hole distortions in two principal strain directions on opposite sides of thin ...
As mentioned at the outset of this book, arriving at practical solutions to many problems in geomechanics requires knowledge of the magnitude and orientation of all three principal stresses. This is well illustrated by the range of geomechanical topics and case studies presented in Chapters 10–12....
Usage: study of physico-mechanical properties of the rocks. SUMMARY OF THE INVENTION: rock sample in coarse-zhayut hydrostatic pressure. The magnitude of the pressure is taken equal to the sum of principal stresses in the investigated burial depth breed axial pressure is increased stepwise and si...
Application of this method confirms the results derived with the analysis described above. Additionally, the evaluation of the orientation of the fractures with respect to the wellbore axis indicates that over major depth sections of the investigated wells the vertical stress is a principal stress. ...
The developed procedure is based on a FEM supported continuous simulation of the nanoindentation, enabling the determination of stress distribution development in the coating during the indenter penetration. Herewith, the principal and equivalent stresses at various positions in the coating material at the...
