9. J modeling#
Closed crack bottom, calculation of \(G\) for incompressible elements.
9.1. Characteristics of modeling#
Identical to modeling A except the elements used are 3D_ INCO_UPG.
9.2. Characteristics of the mesh#
Identical to modeling A
9.3. note#
The keyword SYME is used in the CALC_G operator to automatically multiply by two the energy restoration rate calculated on a single lip of the crack, when the FOND_FISS operand is absent. When FOND_FISS is present, symmetry information is retrieved directly from the fond_fiss concept created via DEFI_FOND_FISS.
9.4. Tested sizes and results#
