Bending Calculator - Solution-NG Engineering

Input Parameters

Input Mode

r = inner radius, R = outer radius, s = material thickness

Inner Radius (r) - mm

Material Thickness (s) - mm

Bend Angle (degrees)

K-Factor Calculation Method

Neutral Radius (Rn) - mm

Rn must be between r and R

Auto X0 Calculation Ranges

r/s ≤ 0.1

→ X₀ = 0.32

0.1 < r/s ≤ 0.25

→ X₀ = 0.35

0.25 < r/s ≤ 0.5

→ X₀ = 0.38

0.5 < r/s ≤ 1

→ X₀ = 0.42

1 < r/s ≤ 2

→ X₀ = 0.455

2 < r/s ≤ 3

→ X₀ = 0.470

3 < r/s ≤ 4

→ X₀ = 0.475

r/s > 4

→ X₀ = 0.5

BD = 2 × OSSB - BA

OSSB = tan(α/2) × (R + s)

K = (Rn - r) / (R - r)
