Result Interpretation

Moisture-Driven Orthotropic Hygroscopic Strain Predictor for Structural Timber calculator computes Orthotropic hygroscopic strain in m/m using the defined engineering formula and the input values provided. Orthotropic hygroscopic strain is expressed in m/m. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Current moisture content = 0.1
  • Reference moisture content = 0.08
  • Longitudinal hygroscopic coefficient = 4.5E-5
  • Radial hygroscopic coefficient = 0.0021
  • Tangential hygroscopic coefficient = 0.0037

Expected Result:

  • Orthotropic hygroscopic strain = 0.000117
