VL-MOD-GEO-001IMPLEMENTEDSCREENING ONLY

K0 / Rankine continuum screening

Regolith / geotechnics · LUNA K0 / Rankine screening · version 0.1

Purpose
Provide at-rest and Rankine-type lateral pressure screening for buried circular shells.
Source
Classical continuum earth-pressure relations applied as lunar screening tools.
Validity range
Order-of-magnitude lateral-load screening. Not nonlinear contact analysis.
Uncertainty
Low-gravity strength, dilation and ice content are not represented.

Assumptions

  • Continuum soil
  • K0 and Rankine limiting states used as bounds, not as unique physical truth

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.
