zone.tri.strain.increment

Syntax

t := zone.tri.strain.inc(z<,ioverlay><,itri>) (2D ONLY)

Get the zone triangle strain increments based on the current displacement field.

If ioverlay is specified (an integer from 1 to 2) then only the strain increments of the triangle of that overlay are returned. If itri is specified as well, then only the strain increments of that specific triangle is returned.

The total number of triangle in each overlay depends on the zone type (quadrilateral or triangle). See also the functions zone.overlays and zone.tri.num.

Returns:

t - zone triangle strain increment tensor or value

Arguments:

z - zone pointer

ioverlay - the overlay index of the triangle, from 1 to 2

itri - the index of the triangle in the overlay

Component Access

f := zone.tri.strain.increment (z)->xx

f := zone.tri.strain.increment.xx(z)

Get the \(xx\)-component of the zone triangle strain increments based on the current displacement field.

Returns:

f - \(xx\)-component of the zone triangle strain increment tensor or 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.tri.strain.increment(z,<int>,<int>,<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.tri.strain.increment.yy(z)

f := zone.tri.strain.increment.zz(z)

f := zone.tri.strain.increment.xy(z)

f := zone.tri.strain.increment.xz(z)

f := zone.tri.strain.increment.yz(z)
