fl

Fatigue.fl(nloc='', node='', scfx='', scfy='', scfz='', title='', **kwargs)

Defines a set of fatigue location parameters.

Mechanical APDL Command: FL

Parameters:

nlocstr

Reference number for this location (within MXLOC ). When defining a new location, defaults to lowest unused location. If the specified NODE is already associated with a location, NLOC defaults to that existing location.

nodestr

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). If NODE = -1 (or redefined), erase all parameters and fatigue stresses for this location.

scfxstr

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.

scfystr

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.

scfzstr

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.

titlestr

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.
