Average Shrinkage Values Of Wood At Various Moisture Content

It calculates at 3 preset values and one for the moisture content you desire to dry your wood to.
The fiber saturation point (FSP) is preset @ 30. This based on that in most publications this is used as an average value but 28% for North American species sounds like a better option. The FSP for some of the tropical species appear to be much lower.


Shrinkage @ Various % Moisture Content

Tangential Shrinkage %
Radial Shrinkage %
Volumetric Shrinkage %
Moisture Content %
Fiber Saturation Point %

Results:

Shrinkage @ 20% MC Tang % Rad % Vol %
Shrinkage @ 15% MC Tang % Rad % Vol %
Shrinkage @ 6% MC Tang % Rad % Vol %
Shrinkage @ Selected MC Tang % Rad % Vol %
TS/TR Ratio #

The Calculation

  1. enter the total tangential shrinkage %
  2. enter the total radial shrinkage %
  3. enter the total volumetric shrinkage %
  4. enter the desired moisture content
  5. enter the fiber saturation point of the wood species (preset @ 30%)

The Results

  1. shrinkage of wood dried to 20 % MC
  2. shrinkage of wood dried to 15 % MC
  3. shrinkage of wood dried to 6% MC
  4. shrinkage of wood dried to your selected % MC
  5. TS/TR ratio
