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
