Use the Stress Linearization node to define a line (
stress classification line;
SCL) along which a linearization of the stress state will be made. A number of result variables are created for each SCL. Add one
Stress Linearization node for each SCL along which you want to compute linearized stresses.
When a Stress Linearization node has been added, you do not need to compute a new solution. It is sufficient to perform an
Update Solution to make the variables for the new SCL available.
The Stress Linearization node is only available with some COMSOL products (see
http://www.comsol.com/products/specifications/).
Select Reference point or
Orientation vector. When a reference point is used, the second local direction will be in the plane formed by the SCL and the selected point. When an orientation vector is used, the second local direction will be directed in the plane formed by the SCL and the selected orientation. The orientation is always adjusted so that it is orthogonal to the SCL.
