Linear buckling

Read the published element combinations and their limitations. Each row retains its 0.2.8 status; implementation updates do not automatically promote qualification.

Inherited evidence within the recorded scope; no new promotion is implied.

Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 is PASS_WITH_LIMITATIONS; external coverage is bounded and other analysis scopes remain separately governed. No nonlinear collapse claim; 0.2.6 maturity extension is pending.

Inherited evidence within the recorded scope; no new promotion is implied.

Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 internal quantitative and analytical evidence is present; comparable independent external deck remains pending. No nonlinear collapse claim; 0.2.6 maturity extension is pending.

  • EXPERIMENTAL does not mean QUALIFIED_BOUNDED, normal-use or production-ready.
  • No general Euler prediction or convergence claim is made; WP06/WP06B Euler and convergence FAIL records remain visible.
  • No certification, imperfections, nonlinear/post-buckling, plasticity, arbitrary-mesh, universal-accuracy, multi-mode or mixed-mesh claim.
  • No external correlation claim; current comparable Code_Aster/CalculiX evidence was unavailable.
  • HEX8R, SRI, B-bar and hourglass formulations are excluded.

Historical source note: G14 explicitly retains HEX8 buckling as more-evidence-required. G05 internal quantitative and analytical evidence is present; comparable independent external deck remains pending. No nonlinear collapse claim; 0.2.6 maturity extension is pending.
