Factor of Safety
The Factor of Safety PropertyManager
allows you to assess the safety of solid and shell models (sheet
metals and surfaces) based on a failure criterion.
Factor of Safety - Step 1 of 3
Component
. For assemblies and multibody parts, select All,
or select a component or body from the menu.
Criterion
. Failure criteria:
Composite Options
Failure criteria for composites.
(Available for models with composite shells only)
Property
Include
title text. Lets you type a custom title for the plot.
Associate
plot with name view orientation. Associates a predefined view orientation
with the active plot.

Factor of Safety - Step 2 of 3
If you selected Mohr-Coulomb stress criterion from
the previous step, you must set the tensile
and compressive stress limits.
Multiplication factor. Allows you to enter a multiplication factor
for calculating the selected stress limit. For example, if you apply a
factor of 0.5 to a yield strength stress limit of 2000 psi, Factor of
Safety uses 0.5 x 2000 = 1000 psi for the stress limit.

Shell Results
. Available for shells
only. Select the shell face for which you want to perform the Factor of
Safety:
Top
Bottom
Minimum
Maximum
You should run two checks: one for the top face, and the other
for the bottom face.
Composite Options
Available for models with composite shells only.
Worst-case across all
plies. Envelope plot for minimum FOS
across all plies (including top and bottom faces of every ply).
Ply number.
Allows you to select the ply number for the factor of safety output. This
option is not available when Worst-case across all plies is selected. You can select the top or bottom
face for the selected ply number.

distribution. Plots the distribution of the factor of safety.
Areas below factor
of safety. Plots the regions below the specified factor of safety
(displayed in red color). Regions above the specified factor of safety
are displayed in blue color.

Lists the minimum factor of safety based on the selected criterion.
