Bend Deduction Calculator

Bend allowance (BA):

K-factor (K):

Bend radius (ε):

Material thickness (T):

Bend angle (θ):

How This Is Calculated

$$ BD = 2 \cdot (R + K + T) \cdot tan \left(\frac{\theta}{2}\right) $$ where:

BD = Bend deduction (m)

R = Bend radius (m)

K = K-factor (dimensionless)

T = Material thickness (m)

θ = Bend angle (rad)

Assumptions

The neutral axis is located halfway through the thickness of the material.
The bend radius is constant throughout the bend.
The thickness of the material is uniform.
Springback is not considered.
