A material orientation plot shows the material directions of
elements in the model at the element integration points.
The material orientations are plotted at a specified step and
frame of the analysis and at a specified section point for shell elements.
Material orientation plots can also be created to show the material directions
of reinforcements (rebar orientation) in membrane, shell, and surface elements.
Abaqus/CAE
represents the material orientations as triads. This section explains material
orientation plotting.
