Visualization of Geologic Stress Perturbations Using Mohr Diagrams

IEEE Transactions on Visualization and Computer Graphics, 2005
Huge salt formations, trapping large untapped oil and gas reservoirs, lie in the deepwater region of the Gulf of Mexico. Drilling in this region is high-risk and drilling failures have led to well abandonments, with each costing tens of millions of dollars. Salt tectonics plays a central role in these failures. To explore the geomechanical interactions

Residual stress diagram for electrodeposited zinc coatings

Surface Technology, 1979
Abstract A method for plotting residual stress diagrams (stress as a function of thickness) is described. An application of this method for the cases of tensile and compressive average (over the thickness) stress is demonstrated. The validity of the method and the results are discussed.

Segmented models for stress-strain diagrams

Wood Science and Technology, 1989
Tension and compression stress-strain data from tests of wood specimens were mathematically described by 2- or 3-segment models, respectively. Three or four parameters are required by the segmented models, but these are easily obtained from regression analysis of the digitized data. One required parameter is Young's modulus. The model parameters varied

Temperature–stress phase diagram of strain glass Ti48.5Ni51.5

Acta Materialia, 2008
Abstract The temperature and stress dependence of the properties of a recently discovered strain glass Ti 48.5 Ni 51.5 , which is a glass of frozen local lattice strains, was investigated systematically. It was found that the ideal freezing temperature ( T 0 ) of the strain glass decreases with increasing stress.

On Generalized Reciprocal Diagrams for Self-Stressed Frameworks

International Journal of Space Structures, 2008
We present the duality between edge lengths and axial forces in self-stressed frameworks, upon which are based reciprocal diagrams, introduced by Maxwell and Cremona in the nineteenth century. The main concepts and principles are simplified by using a graph theoretic approach.

Tangential stress range–compressive stress range diagram for fretting fatigue design curve

Tribology International, 2011
Abstract Fretting fatigue strength can be effectively predicted regardless of pad geometry, rigidity, contact pressure and slip amplitude based on the tangential stress range–compressive stress range diagram. However, the tangential stress range–compressive stress range diagram is a material property and applicable only to the material concerned.

Ti-Ni Phase Diagram with Applied Stress

MRS Proceedings, 1993
ABSTRACTThe role of stress on the phase evolution of thin-film TiNi has not been investigated and may play an important role in the phase evolution of thin film TiNi. In this paper, a preliminary set of phase diagrams for Ni-Ti at different pressures are presented relating the stability of the stoichiometric TiNi phase to the other well-documented ...

Constructing critical stress diagrams for anisotropic brittle materials

Soviet Materials Science, 1971
The problem of critical equilibrium in a plate with a crack in biaxial tension/compression was analyzed for the case in which the plate material is brittle and anisotropic with respect to its breaking stress. The obtained solutions were used to construct critical state diagrams for brittle solids of this kind.

The rate of shear‐shearing stress diagram (D‐τ diagram) of plastic suspensions

Recueil des Travaux Chimiques des Pays-Bas, 1943
Abstract The plastic behaviour of suspensions is considered from the point of view of energy, of structure and of mechanics. According to this method of consideration the systems which exhibit so‐called Ostwald structural viscosity (Ostwald systems) are to be conceived of as suspensions with elastically deformable micelles, while the so‐called Bingham ...
