Title
Defines a set of fatigue location parameters.
NLOC
Reference number for this location (within
MXLOC
). When defining a new location, defaults to lowest unused location. If the specifiedNODE
is already associated with a location,NLOC
defaults to that existing location.NODE
Node number corresponding to this location (must be unique). Used only to associate a node with a new location or to find an existing location (if
NLOC
is not input). IfNODE
= -1 (or redefined), erase all parameters and fatigue stresses for this location.SCFX
,SCFY
,SCFZ
Stress concentration factors applied to the total stresses. Factors are applied in the global X, Y, and Z directions unless the axisymmetric option of the FSSECT is used (that is,
RHO
is nonzero), in which case the factors are applied in the section x, y, and z (radial, axial, and hoop) directions.Title
User-defined title for this location (up to 20 characters).
Notes
Repeat FL command to define additional sets of location parameters
(MXLOC
limit), to redefine location parameters, or to delete
location stress conditions.
One location must be defined for each node of interest and only one node can be associated
with each location. See the FTSIZE command for the maximum locations
(MXLOC
) allowed. A location will be automatically defined for a
node not having a location when the FSSECT, FSNODE, or FS command is issued. Automatically
defined locations are assigned the lowest available location number, unity stress
concentration factors, and no title.
