fs#

Fatigue.fs(node='', nev='', nlod='', stitm='', c1='', c2='', c3='', c4='', c5='', c6='', **kwargs)#

Stores fatigue stress components at a node.

Mechanical APDL Command: FS

Parameters:
nodestr

Node number corresponding to this location. Used only to associate a node with a new location or to find an existing location.

nevstr

Event number to be associated with these stresses (defaults to 1).

nlodstr

Loading number to be associated with these stresses (defaults to 1).

stitmint or str

Starting item number for entering stresses (defaults to 1). If 1, data input in field C1 of this command is entered as the first item in the list; if 7, data input in field C1 of this command is entered as the seventh item in the list; etc. Items are as follows:

  • 1-6 - SX, SY, SZ, SXY, SYZ, SXZ total stress components

  • 7 - Temperature

  • 8-13 - SX, SY, SZ, SXY, SYZ, SXZ membrane-plus-bending stress components.

  • 14 - Time

c1str

Stresses assigned to six locations starting with STITM. If a value is already in one of these locations, it will be redefined. A blank retains the previous value (except in the C1 field, which resets the STITM item to zero).

c2str

Stresses assigned to six locations starting with STITM. If a value is already in one of these locations, it will be redefined. A blank retains the previous value (except in the C1 field, which resets the STITM item to zero).

c3str

Stresses assigned to six locations starting with STITM. If a value is already in one of these locations, it will be redefined. A blank retains the previous value (except in the C1 field, which resets the STITM item to zero).

c4str

Stresses assigned to six locations starting with STITM. If a value is already in one of these locations, it will be redefined. A blank retains the previous value (except in the C1 field, which resets the STITM item to zero).

c5str

Stresses assigned to six locations starting with STITM. If a value is already in one of these locations, it will be redefined. A blank retains the previous value (except in the C1 field, which resets the STITM item to zero).

c6str

Stresses assigned to six locations starting with STITM. If a value is already in one of these locations, it will be redefined. A blank retains the previous value (except in the C1 field, which resets the STITM item to zero).

Notes

Stores fatigue stress components at a node as input on this command instead of from the current data in the database. Stresses are stored according to the event number and loading number specified. The location is associated with that previously defined for this node ( fl ) or else it is automatically defined. May also be used to modify any previously stored stress components. Stresses input with this command should be consistent with the global coordinate system for any fsnode or fssect stresses used at the same location.
