# struct.shell.stress.prin

Syntax

v := struct.shell.stress.prin(p,inode)

Get the resolved principal stress at the current depth factor and position given by inode.

inode = 0 indicates the element centroid, while inode = 1 to 3 indicates the positions of the nodes with those indices.

Note that compressive stresses are negative in FLAC3D.

Returns: v - position vector or component p - a shell element pointer inode - index of the location of the resultant, from 0 to 3
