# Thin-wall pressure stress screening
# Scope: Thin cylinder membrane hoop stress; no ends or stress concentrations.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

pressure = 1 MPa
diameter = 100 mm
thickness = 2 mm

hoop := pressure*diameter/(2*thickness) [MPa]
wallRatio := thickness/diameter

check thin wall screen: wallRatio <= 0.05

scenario alternative: pressure = 0.8 MPa
