The phrase "axis of stress" is correct and usable in written English.
It can be used in contexts related to physics, engineering, or psychology, where stress is analyzed or discussed in relation to a specific axis or direction.
Example: "In structural engineering, understanding the axis of stress is crucial for ensuring the stability of the building under various loads."
Alternatives: "line of stress" or "direction of stress".
Fig. 1 Dilatancy: increasing stress causes cracks in the rock, which enlarges the material perpendicular to the main axis of stress.
For a random sample, it is possible to deduce the form of the function φ that describes the average contribution to the shift produced by a chain making angle θ to the axis of stress.
Dynamic stimulation of cells/gelatine constructs during 14 days (80 cycles/min with a 20% deformation of the initial length) generated a marked increase in cell proliferation, improved spatial cell distribution throughout the scaffold, and markedly increased the total amount of newly synthesized collagen matrix with fibres aligned in parallel to the axis of stress.
The axis of maximum stress (s1) lies in the horizontal plane and the axis of minimum stress (s3) in the vertical plane indicating thrust faulting.
Two polarizers that are crossed ordinarily do not transmit light, but if a stressed material is placed between them and if the principal axis of the stress is not parallel to this plane of polarization, some light will be transmitted in the form of coloured fringes.
It is shown that velocity variations along maximum stress is more informative at elastic phase of rock deformations (velocity increases), whereas velocity variations along axis of minimum stress is more informative at the stage of nonlinear deformation of rock (velocity begin decrease).
This, in turn, means that the "fast" direction of shear waves should also be oriented subparallel to the axis of maximum stress (Crampin 1978).
In this model, shear-wave splitting in the crust is caused by the orientations of faults or cracks, and it is thought that propagating cracks are preferentially aligned subparallel to the orientation of the axis of maximum stress.
Results highlight the orthotropic behavior of FDM components and suggest that tensile performance is improved by aligning fibers of unidirectional laminae more closely with the axis of applied stress.
According to the Dilatancy theory, a substantial change (increase in the perpendicular direction to the main axis of the stress) in the rock properties will occur shortly before earthquake leading to the possibility of water penetration in the cracks and/or the number of cracks increases exponentially.
This faulting suggests dip slip reverse motion, and to a horizontal east-west axis of confining stress.
