RATE
RATE, Option
Specifies whether the effect of creep strain rate will be used
in the solution of a load step.
-
Option Activates implicit creep analysis.
0 or OFF
—
No implicit creep analysis. This option is the default.
1 or ON
—
Perform implicit creep analysis.
Notes
Set Option = 1 (or ON) to perform an implicit creep analysis
(TB,CREEP with TBOPT 
1). For viscoplasticity/creep analysis, Option
specifies whether or not to include the creep calculation in the solution of a load step. If
Option = 1 (or ON), the program performs the creep calculation. Set
an appropriate time for solving the load step via a
TIME,TIME command.
Product Restrictions
This command works only when modeling implicit creep with either von Mises or Hill potentials.
When modeling implicit creep with von Mises potential, you can use the following elements: LINK180, SHELL181, PLANE182, PLANE183, SOLID185, SOLID186, SOLID187, SOLID272, SOLID273, SOLID285, SOLSH190, BEAM188, BEAM189, SHELL208, SHELL209, REINF264, SHELL281, and ELBOW290.
When modeling anisotropic creep (TB,CREEP with TB,HILL), you can also use the following elements: LINK180, SHELL181, PLANE182, PLANE183, SOLID185, SOLID186, SOLID187, BEAM188, BEAM189, SOLSH190, SHELL208, SHELL209, REINF264, REINF265, SOLID272, SOLID273, SHELL281, SOLID285, PIPE288, PIPE289, and ELBOW290.
