deviatoric

We now wish to extend the work to study the effect of deviatoric stress.

In this case, the deviatoric part of is modeled as:

The deviatoric stress is transferred to the sample through the σ1 piston.

At no stage was a deviatoric stress applied to the permafrost specimens.

The divergence of the deviatoric stress is given by:

The quadratic Hill yield criterion depends only on the deviatoric stresses and is pressure independent.

A particular type of piston-cylinder, called Griggs apparatus, is also able to add a deviatoric stress on the sample.

This yields volumetric and deviatoric stress-strain relations similar to Eq.

Deviatoric stresses are directed stresses, acting in particular directions.

The results showed that the minimum creep strain rate increases exponentially with increasing temperature and applied deviatoric stress.

Computer models suggest the normal faults in the area are most vulnerable to deviatoric stress loading by filling in of water.

Deviatoric stress and differential stress can only be equal under isotropic stress conditions.

The Mohr-Coulomb failure surface is a cone with a hexagonal cross section in deviatoric stress space.

Ore zones formed in areas of low deviatoric stress along steeply dipping pluton margins.

Failure along the pluton margin and foliation caused the development of zones of low deviatoric stress.

Note that the term "differential stress" should not be confused with "deviatoric stress" (Engelder, 1994).

(c) The plastic strain increment is proportional to the respective deviatoric stress:

The octahedral plane is sometimes referred to as the 'pi plane' or 'deviatoric plane'.

Engelder, T. (1994): Deviatoric stressitis; a virus infecting the earth science community.

The chief model limitations are the use of a circular deviatoric plane and the assumption of symmetry about the hydrostatic axis.

The forms are termed the deviatoric parts of the respective tensors, while are called the dilatational parts.

The right side of the equation is in effect a summation of body forces (such as gravity) and divergence of deviatoric stress.

Ice viscosity is stress-dependent, and in zones where the (deviatoric) stresses are low, the viscosity becomes very high.

The mean stress increase beneath the reservoir appears to be small, but increasing the deviatoric stress permits Mohr-Coulomb failure.

The other common technique of deviatoric stress determination utilizes differential lattice strains and single crystal elastic constants.
