# Creep deformation estimate
# Scope: Constant measured creep strain rate at a fixed temperature and stress.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

rate = 0.00000001 s^-1
duration = 100 h
length = 100 mm

strain := rate*duration
elongation := strain*length [mm]

check creep strain budget: strain <= 0.01

scenario alternative: rate = 8e-09 s^-1
