VNV-MITC4-LAMINATE-DYNAMIC-001¶
Objet¶
Coherence interne modal, Newmark et harmonique pour un porte-a-faux MITC4 stratifie symetrique [0/90/90/0]. Cette campagne ne constitue pas une correlation externe.
Modal¶
Frequence fondamentale : 14.002555 Hz. Residu relatif : 1.839e-09. Orthogonalites masse/raideur : 9.174e-16 / 4.624e-11.
Newmark¶
| Pas/periode | Erreur RMS | Derive energie | Residu dynamique | Max S11 face superieure (Pa) |
|---|---|---|---|---|
| 20 | 4.162e-02 | 8.602e-12 | 3.978e-12 | 3.211e+03 |
| 40 | 1.048e-02 | 3.554e-12 | 4.638e-12 | 3.212e+03 |
| 80 | 2.623e-03 | 4.119e-12 | 4.506e-12 | 3.212e+03 |
Harmonique¶
Erreur complexe maximale : 2.069e-10. Limite statique a 0 Hz : 5.375e-12. Post-traitement : 4 plis.
Limites ouvertes¶
- The oracle is the first numerical laminate eigenmode; this is an algorithmic invariant, not an independent structural reference.
- No same-mesh Code_Aster, CalculiX, Abaqus or NAFEMS laminate-dynamics correlation is supplied.
- The layup is planar. Curved laminates, eccentric shell offsets, nonlinear plies, damage and delamination are outside this evidence.
- Only mass-proportional Rayleigh damping is exercised because drilling directions are statically condensed.
