Stress linearization is the separation of stresses through a section into constant membrane and linear bending stresses. 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.
