Bend Allowance Calculator — Frequently Asked Questions
Q1 What is the K-factor in sheet metal bending? ▾
The ratio of the neutral axis location relative to material thickness (K = t_neutral / T).
Q2 Why does metal stretch during bending? ▾
Outer fibers experience tension while inner fibers experience compression; the neutral axis preserves original unelongated length.
