Stress linearization is the separation of stresses through a
section into constant membrane and linear bending stresses. Stress
linearization is available for output databases only.
To linearize stresses in
Abaqus/CAE,
the following procedure is used:
You define a section through your model. You specify the endpoints of
the section by selecting nodes in the model, coordinates in space, or a saved
path.
Abaqus/CAE
defines the stress line by interpolating between the two endpoints to obtain a
user-specified number of equal intervals along a straight line.
You can save the stress line as a path; the saved path includes the
endpoints and each interval point along the stress line. If you save the stress
line as a path,
Abaqus/CAE
always creates a point list path, regardless of the method that you used to
define the endpoints.
The specified stress results are obtained at equally spaced intervals
along the line in a local coordinate system defined by the line.
Abaqus/CAE
performs stress linearization calculations and displays the results in the form
of an X–Y plot. You can choose to save the data
and/or to write it to a file.
If you linearize stresses across multiple part instances, the results will
be averaged for any points that exist in more than one part instance.
To obtain linearized stresses along a line, select
ToolsQuery
from the main menu bar, then select Stress linearization
from the Visualization Module Queries options.
