Safety (for Fasteners)
Add a Safety subnode to a Fasteners node in order to evaluate the safety margin against failure of the individual fasteners.

•
The Critical normal force, Fn,max
•
The Normal force failure exponent, αn
•
The Critical shear force, Fs,max
•
The Shear force failure exponent, αs
The failure criterion is assumed to be a power law of the type
In the Warning Level section, select either Safety factor or Margin of safety. Then enter either the safety factor sf0, or the margin of safety, ms0. The relation between the two is
When using any of these option, a warning level is defined by the criterion
The purpose of the settings in this section is to make it possible to flag fasteners as dangerous, even if the load is less that the failure load.
