Webspherical stress. [ ′sfir·ə·kəl ′stres] (mechanics) The portion of the total stress that corresponds to an isotropic hydrostatic pressure; its stress tensor is the unit tensor … WebThe simplest way to estimate the Pulay stress is to relax the structure with a large basis-set ( default cutoff is usually sufficient, or PREC = High in VASP.4.4). Then re-run VASP for the final relaxed positions and cell parameters with the default cutoff or the desired cutoff. Look for the line 'external pressure' in the OUTCAR file:
In continuum mechanics, the Cauchy stress tensor $${\displaystyle {\boldsymbol {\sigma }}}$$, true stress tensor, or simply called the stress tensor is a second order tensor named after Augustin-Louis Cauchy. The tensor consists of nine components $${\displaystyle \sigma _{ij}}$$ that … Zobraziť viac The Euler–Cauchy stress principle states that upon any surface (real or imaginary) that divides the body, the action of one part of the body on the other is equivalent (equipollent) to the system of distributed forces and … Zobraziť viac At every point in a stressed body there are at least three planes, called principal planes, with normal vectors The components Zobraziť viac The maximum shear stress or maximum principal shear stress is equal to one-half the difference between the largest and smallest principal stresses, and acts on the plane that … Zobraziť viac Considering the principal directions as the coordinate axes, a plane whose normal vector makes equal angles with each of the principal axes (i.e. having direction cosines equal to $${\displaystyle 1/{\sqrt {3}} }$$) is called an octahedral plane. There are a total … Zobraziť viac The state of stress at a point in the body is then defined by all the stress vectors T associated with all planes (infinite in number) that pass through that point. However, … Zobraziť viac Cauchy's first law of motion According to the principle of conservation of linear momentum, if the continuum body is in static equilibrium it can be demonstrated that the components of the Cauchy stress tensor in every material point in the body … Zobraziť viac The stress tensor $${\displaystyle \sigma _{ij}}$$ can be expressed as the sum of two other stress tensors: 1. a … Zobraziť viac WebThe decomposition of stress and strain tensors into spherical and deviatoric parts is widely used in solid mechanics. For infinitesimal strains, it separates changes of volume from changes of shape. ][ts mechanical importance stems from the fact that, for many solids, the first kind of change depends only on the spheri-
