3. Operands

3.1. Operand TABLE_G

♦ TABLE_G = tab, [table]


This operand allows you to choose the table on which the operations are performed. This table should contain the following 3 columns:

* INST


* G_ ELAS


* G_ PLAS


G_ ELASprovient from the CALC_Gsur command a linear elastic calculation. G_ PLASprovient of the CALC_Gsur command an incremental elastoplastic calculation. The calculation times between the 2 calculations, linear and non-linear, must correspond to column INST.


Note:

* In the 3D case, the user must filter the table from CALC_Gpour to keep only one node of interest, on which the operator will determine the margin factors.

3.2. Operand RESULTAT

♦ RESULTAT = result, [evol_noli]


This operand makes it possible to choose the result of the elastoplastic mechanical calculation, resulting from the command STAT_NON_LINE. This result allows the operator to access the mesh, the model, the material field, which contains the curve KIC, as well as the command variable TEMP.

3.3. Operand GROUP_NO

♦ GROUP_NO = grno, [grno]

This operand makes it possible to define the crack bottom point from which the tables were extracted. This group should contain only one node, which must correspond to the node from which the G values were extracted.


Notes:

* the meshes associated with the node must be affected by a single material, i.e. the bottom node must not be on a material discontinuity.


* The defined material must be filled in with the keyword factor RUPT_FMpour the definition of KIC.
