Preliminary classical buckling screening

Buckling / structural stability · LUNA classical buckling screening · version 0.1

Purpose
Classical buckling estimates for circular shells under pressure and/or overburden-type loads.
Source
Classical shell buckling screening formulae; Vectoris working implementation.
Validity range
Preliminary stability screening. Not a qualified buckling design.
Uncertainty
Knockdown, welds, openings and combined thermal loads remain open.

Assumptions

  • Ideal geometry unless knockdown is explicitly stated
  • Not a nonlinear imperfection-sensitive collapse analysis

Status legend

Implementation status and validation status are independent. IMPLEMENTED means a computational module exists in the LUNA toolchain. It does not mean VERIFIED. CalculiX export is file exchange, not FEM verification.
