Result Interpretation

Sheet Metal K-Factor Estimator from Bend Test Data calculator computes K-Factor in dimensionless using the defined engineering formula and the input values provided. K-Factor is expressed in dimensionless. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Bend Deduction = 0.002
  • Material Thickness = 0.0015
  • Outer Bend Radius = 0.003
  • Bend Angle = 90

Expected Result:

  • K-Factor = -0.42441318157839

Engineering Interpretation:

Under the given input conditions, the calculated result is: K-Factor = -0.42441318157839 dimensionless.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method

k-factor = (bend deduction - 2.0 * (outer bend radius - material thickness)) / (3.14159265358979 * material thickness * bend angle / 180.0)
