zone.stress.effective

Syntax

Tensor Access

f = zone.stress.effective(p,i1<,i2>)

Get the zone effective stress. This is the volume-weighted average of the tetra stresses, plus the zone-averaged pore pressure.

Returns:

t - zone effective stress value
Arguments:

p - zone pointer

i1 - tensor index that, if given without i2, ranges from 1 to 7, accessing the xx, yy, zz, xy, xz, and yz tensor values.

i2 - optional tensor notation that must be given with i1. In this case, i1 corresponds to the first index of the tensor position and i2 to the second in the row/column format. For instance, i1 = 1 and i2 = 3 returns the xz tensor value.

Value Access

f = zone.stress.effective.xx(p)

Get the xx-value of the zone effective stress.

Returns:f - xx-value of the zone effective stress tensor
Arguments:p - zone pointer
f = zone.stress.effective.xy(p)

Get the xy-value of the zone effective stress.

Returns:f - xy-value of the zone effective stress tensor
Arguments:p - zone pointer
f = zone.stress.effective.xz(p)

Get the xz-value of the zone effective stress.

Returns:f - xz-value of the zone effective stress tensor
Arguments:p - zone pointer
f = zone.stress.effective.yy(p)

Get the yy-value of the zone effective stress.

Returns:f - yy-value of the zone effective stress tensor
Arguments:p - zone pointer
f = zone.stress.effective.yz(p)

Get the yz-value of the zone effective stress.

Returns:f - yz-value of the zone effective stress tensor
Arguments:p - zone pointer
f = zone.stress.effective.zz(p)

Get the zz-value of the zone effective stress.

Returns:f - zz-value of the zone effective stress tensor
Arguments:p - zone pointer
