Calculation method
Calculation method
Thin-wall shear flow (N/mm)
Bredt thin-wall closed single-cell approximation q=T/(2Amedian), τ=q/t.
Thin-wall shear stress (MPa)
Bredt thin-wall closed single-cell approximation q=T/(2Amedian), τ=q/t.
Symbols and units

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Bredt thin-wall closed single-cell approximation q=T/(2Amedian), τ=q/t. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
