3. Nonlinear possibilities

3.1. Laws of behavior

The only behavioral relationship available in DYNA_NON_LINE, for the 2D_ FLUI_STRU and AXIS_FLUI_STRU models under COMPORTEMENT is the RELATION “ELAS” (Cf. [U4.51.11]).

3.2. Deformations

Only the linearized deformations keyword “PETIT” under DEFORMATION are available in behavioral relationships (Cf. [U4.51.11]).
