Worked Example
Verified calculation
Given:
- Yield Strength = 250000000
- Elastic Modulus = 200000000000
- Initial Bend Radius = 0.005
- Sheet Thickness = 0.001
Expected Result:
- Springback Angle = 11.9637
Engineering Interpretation:
Under the given input conditions, the calculated result is: Springback Angle = 11.9637 rad.
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
springback angle = (1.0 - (2.0 * yield strength / elastic modulus) * pow((initial bend radius + sheet thickness/2.0) / initial bend radius, 2.0)) * (60.0 * sheet thickness / initial bend radius)Formula family: formula_sheetmetal_springback_angle_calculator
