Fighter Jet — Durability & Damage Tolerance

DaDT substantiation of primary metallic and composite airframe structure on a next-generation fighter. Analysis chain runs from GFEM internal-load extraction through detailed sub-models to fatigue and crack-growth assessment, correlated against coupon and element-level test data.

Key work

  • GFEM-to-sub-model load extraction and detailed FE build of fatigue hot-spots.
  • Allowables curation across multiple material and configuration cases, feeding the global sizing loop.
  • DaDT stress reports authored and released through formal review.
  • Closed design changes that retired hot-spots without breaking the mass budget.
