zone.stress.effective

Syntax

t := zone.stress.effective(z)

Note

• In the description below, the following correspondence is assumed between 3D and 2D analysis:

  • 3D volumes <-> 2D areas

Get the zone effective stress. This is the volume-weighted average of the subzone (tetrahedrals in 3D, triangles in 2D) stresses, plus the zone-averaged pore pressure. Note that compressive stresses are negative.

Returns:

t - zone effective stress value

Arguments:

z - zone pointer

Component Access

f := zone.stress.effective (z)->xx

f := zone.stress.effective.xx(z)

Get the $xx$-component of the zone effective stress. This is the volume-weighted average of the subzone stresses, plus the zone-averaged pore pressure.

Returns:

f - $xx$-component of the zone effective stress value

Arguments:

z - zone pointer

Access other tensor components ($yy$, $zz$, $xy$, $xz$, $yz$) by substituting the component name where $xx$ appears above. See Member Access Operator for information about accessing members from data types using ->.

Deprecated Component Access

Component access by adding an optional integer in the function arguments (zone.stress.effective(z,<int, <int>>)) is deprecated. It remains available but will not be supported in future versions. See Component Access with Integers in FISH on the Deprecated Commands and FISH page for details.

This is hidden. Added to include remaining vector component access functions for inline help.

f := zone.stress.effective.yy(z)

f := zone.stress.effective.zz(z)

f := zone.stress.effective.xy(z)

f := zone.stress.effective.xz(z)

f := zone.stress.effective.yz(z)
