Units 
Sets the stress units.


Set stress limit 
to Yield strength

Sets the stress limit to yield strength.

to Ultimate strength

Sets the stress limit to ultimate strength.

to User defined

Sets the stress limit to a userspecified value.


If you selected MohrCoulomb 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 Wizard uses 0.5 x 2000 = 1000 psi for the stress limit.


Beam Results



Show combined stress on Beams 
For beams, the factor of safety is calculated from: (Upper bound axial and bending stress) / Yield Strength. 

Shell Results 
Select the shell face for which you want to perform the Factor of Safety:
Top


Bottom


Minimum


Maximum


Run two checks: one for the top face, and the other for the bottom face.


Material involved 
Displays the material names and properties related to the stress limits used by Factor of Safety. 

Composite Options
(Available for models with composite shells only.) 
Worstcase 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 Worstcase across all plies
is selected. You can select the top or bottom face for
the selected ply number.
