Nonlinear possibilities ========================== Laws of behavior --------------------- The only behavioral relationship available for this modeling is RELATION 'ELAS' (under COMPORTEMENT) in DYNA_NON_LINE (Cf. [:external:ref:`U4.51.11 `]). Deformations ------------ Only the linearized deformations keyword 'PETIT' under DEFORMATION are available in behavioral relationships (Cf. [:external:ref:`U4.51.11 `]).
