LEARNING OUTCOMES
After the course the student
- Knows the key anatomical features of wood and is able to differentiate between softwood and hardwood and is able to identify several key commercially important species from their microstructures
- Is familiar with the anisotropic structure of wood and is able to describe how the anatomical structure of wood affects its physical and mechanical properties
- Knows the states of water in wood and is able to describe how it affects the mechanical and physical properties of wood
- Knows the relationship between cell wall density, bulk density and void volume (porosity) and can apply this information to predict how fluids may behave in wood
- Is familiar with the thermal characteristics of wood, especially thermal conductivity, heat capacity and diffusivity
- Is familiar with the acoustic properties of wood and how this might be utilised in non-destructive testing and construction
- Is familiar with the electrical properties of wood
- Is familiar with the combustion properties of wood and its fire performance
- knows about the short-term mechanical properties of wood and how structure/anatomy, density and moisture affect these
- Is familiar with the long-term behaviour of wood under static and cyclical loading
- Is able to describe the key steps in the manufacture of the major wood products (solid wood, wood-based composites and engineered wood)
