Safety
Add the Safety subnode to a Linear Elastic Material to set up variables which can be used to check the risk of failure according to various criteria. Four different variables describing the failure risk are defined, as described in Table 6-17
You can add any number of Safety nodes to a single material model. The contents of this feature do not affect the analysis results as such, so you can add Safety nodes after having performed an analysis, and just do an Update Solution in order to access to the new variables for result evaluation.
For orthotropic and anisotropic failure criteria, the directions are given by the coordinate system selection in the parent node.
Shell Properties
Select the layer or layers for which the safety factor variables are to be defined.
When Use all layers is not selected.
Each Safety subnode defines its own set of variables, so there is no interaction if you add several such nodes with the same selection.
All other settings for the Safety node are described in the documentation for Safety in the Solid Mechanics interface.
