About this course

Tree growth and wood properties: Relationships between silviculture, tree growth, wood morphology and wood properties.

Wood physics: Density, wood-water relations, capillary movements and diffusion, thermal, electrical and acoustical properties, and dynamic behaviour.

Mechanics and rheology of wood: Elasticity (stress and strain), orthotropic elasticity, plasticity, creep, crushing strength, bending strength, shock resistance, torsional properties, and shear strength. Wood decay mechanisms with emphasis on biological decay

Learning outcome


The student should have advanced knowledge about the properties of wood and how these may relate to the use of wood in different applications. The student should know how to relate this to the chemistry and anatomy of wood, and further how this depend on silviculture and tree growth. The student should have knowledge about scientific theory and methods to do research in the field.


The student should know how to accomplish scientific wood property studies. The student should know how to behave critically to different information and how to use the information to structure and make reasonings with in the field. The student should be able to analyze data with statistical software.

General competence:

The student should know how to convey and exchange opinions within the field, both in written and orally. The student should be able to find and use knowledge on new areas within the field.

  • Lectures, exercises, more and less extensive written assignments, excursion. The exercises are used to concretise the theoretical material. The students must present some of the papers in class. In addition, the students will be given a number of questions related to the course which they voluntarily can answer and get feedback on during the course.
