Swelling

Glossary Term

Swelling is a physical process in which a substance (usually a liquid, but also gases or vapors) penetrates into a solid body and causes the increase in volume of the solid body.
In civil engineering, stresses can be induced by swelling of unrestrained structural components (especially timber), which must be considered in the structural analysis.
The moisture can only be absorbed in timber if the air humidity deviates from the timber equilibrium moisture. There must be a moisture gradient between the timber and the environment.
