Bend Allowance
Bend allowance, abbreviated as BA, is the length of the arc through the bend area at the neutral axis.

\(\large{ BA = \frac{\theta \; \pi}{180} \; \left( r \;+\; K \; t \right) }\) | ||
Symbol | English | Metric |
\(\large{ BA }\) = bend allowance | \(\large{in}\) | \(\large{mm}\) |
\(\large{ \theta }\) (Greek symbol theta) = bend angle | \(\large{deg}\) | \(\large{rad}\) |
\(\large{ r }\) = inside radius | \(\large{in}\) | \(\large{mm}\) |
\(\large{ K }\) = K-factor | \(\large{dimensionless}\) | |
\(\large{ t }\) = material thickness | \(\large{in}\) | \(\large{mm}\) |
