`struct.beam.plastic.ipstress`

Syntax

- f := struct.beam.plastic.ipstress(p,ipnum) (currently 3D ONLY)
Get stress at integration point of an element with a plastic material model. Each beam element with a plastic material model has a number of integration points distributed throughout its volume, and each of them tracks its axial stress (\(\sigma_{xx}\)). The integration point locations are shown in the beams with rectangular and circular cross-sections illustrated in Beam Structural Elements.

- Returns:
f - axial stress

- Arguments:
p - pointer to a beam-type element

ipnum - integration point number for beams with rectangular- or circular cross-sections
