struct.beam.plastic.ipstrain

Syntax

f := struct.beam.plastic.ipstrain(p,ipnum) (currently 3D ONLY)

struct.beam.plastic.ipstrain(p,ipnum) := f

Get strain at integration point of a beam element with a plastic material model. Each beam element with a plastic material model has integration points distributed throughout its volume, and each of them tracks its axial strain. The strain is not tracked for elements with an elastic material model.

Returns:

f - strain (axial component \(\varepsilon_{xx}\) in element coordinate system)

Accepts:

f - strain (axial component \(\varepsilon_{xx}\) in element coordinate system)

Arguments:

p - pointer to a beam-type element

ipnum - integration point number as shown here and here
