Worked Example

Verified calculation

Given:

  • Paper elastic modulus = 3500000000
  • Sheet thickness = 0.0001
  • Paper Poisson's ratio = 0.3
  • Moisture-induced axial strain gradient = 0.002
  • Moisture sensitivity coefficient of modulus = 1.2E-10

Expected Result:

  • Equilibrium curl radius = 0.054166666666667

Engineering Interpretation:

Under the given input conditions, the calculated result is: Equilibrium curl radius = 0.054166666666667 m.

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.
