VNV-MITC3-LAMINATE-DYNAMIC-001¶
Objet¶
Verification interne MITC3+ multicouche plane symetrique [0/90/90/0]. La campagne combine un patch membranaire analytique et des invariants modaux/dynamiques. Elle ne constitue pas une correlation externe.

| 16 | 7.562e-14 | 4 |
| 64 | 8.477e-13 | 4 |
Modal¶
Frequence fondamentale : 13.934772 Hz. Residu relatif : 1.347e-09. Orthogonalites masse/raideur : 7.022e-16 / 7.577e-12.
Newmark¶
| Pas/periode | Erreur RMS | Derive energie | Residu | Plis finaux |

| 80 | 2.623e-03 | 2.154e-12 | 1.672e-12 | 4 |
Harmonique¶
Erreur complexe maximale : 6.313e-09. Limite statique a 0 Hz : 1.884e-14. Post-traitement : 4 plis.
Limites ouvertes¶
- The static oracle is an affine membrane field and the dynamic oracle is the first computed mode; neither is an external structural comparison.
- No same-mesh Code_Aster, CalculiX, Abaqus or published ply-level dynamic correlation is supplied.
- The layup is planar and symmetric. Curved laminates, non-zero B coupling, offsets, damage, delamination, large rotations and nonlinear dynamics are outside this evidence.
- Nodal dynamic shell-stress histories are intentionally not requested for MITC3+ across non-aligned local frames; element and ply results remain available at each stored state.
