Content (Syllabus outline)

  • Wood - an environmentally friendly material.
  • Wood as hetero-capillary system with a typical composite structure at the macromolecular, submicroscopic, microscopic and macroscopic level.
  • Density, porosity, and wood moisture content; phase equilibrium and phase changes.
  • Sorption thermodynamics: enthalpy, entropy and Gibbs free enthalpy (energy) of free and bound water, wetting and heat of sorption (differential and integral); hydro expansion (swelling) pressure.
  • Hydro expansion – hydro elastic effect and stress states.
  • Thermal, electrical and acoustical characteristics of the wood - non-destructive study of wood structures and properties.
  • Elasto mechanic properties of wood as an orthotropic material.
  • Visco-elasticity of wood and stress relaxation in thermo-mechanical processes.
  • Fracture mechanics of wood; linear elastic fracture mechanics (LEFM), Numerical and experimental characterization methods of wood.
  • Strength of wood - a hierarchical structure of wood and characterization of mechanical properties, criteria for assessing the strength of timber - Methods for ultimate limit states and serviceability EC 5.
  • Evaluation of the relevant properties of wood; variability of physical and mechanical properties of wood (in the tree, between trees, juvenile, adult wood, reaction wood).
