The XLOT measurement is a reliable method for determining horizontal stresses in the normal or strike-slip faulting stress regime. Some theoretical methods to estimate the minimum and maximum horizontal stresses are … WebbThe strain equation above can be converted to stress by using Hooke's law, σ = Eε, giving, σ = -Ey/ρ (1) There is still the issue of not knowing the radius of curvature, ρ. If one thinks about it, the radius of curvature and the bending moment should be related.
WebbResolved shear stress (RSS) is the shear component of an applied tensile or compressive stress resolved along a slip plane that is other than perpendicular or parallel to the … WebbA single equation is used for the stress‐strain equation. The model allows for cyclic loading and includes the effect of strain rate. The influence of various types of confinement is taken into account by defining an effective lateral confining stress, which is dependent on the configuration of the transverse and longitudinal reinforcement.
