# Scope: Longitudinal outer-fiber bending strain; springback and forming sequence omitted.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

thickness = 1 mm
neutralRadius = 20 mm

strain := thickness/(2*neutralRadius)

check supplied strain budget example: strain <= 0.03

scenario alternative: thickness = 0.8 mm
