Aims of the course:
Knowledge of the properties of wood and wood-based materials as a prerequisite for the rational choice of processing technology and use of wood for structural applications in construction, furniture making and inhabited environments. Mastering the fundamentals of materials engineering - understanding the relationship between chemical composition and anatomical structure and properties of wood.
Application of structural analysis on natural non-homogenous anisotropic polymer - wood. The course focuses on description of relationships among chemical composition, anatomical structure and response of wood to loading. Student will be provided: 1) theoretical description and analysis of general stress and strain state - general Hooke's law related to the dimensions of a problem, introduction to a fracture mechanics, rheological properties of wood and mechanics of layered systems; 2) in practical lectures, students will evaluate gained theoretical concepts by a set of measurement of material properties that describe stress and strain behavior of wood when loaded by fundamental modes of loading. Advanced chapter is mathematical and physical evaluation of behavior of wood on microscopic scale within which students can use contemporary knowledge of chemical and anatomical structure of wood to learn an influence of boundary conditions on mechanical properties of wood on macroscopic scale. After passing the course, students will be able to evaluate a reason of material failure and design the optimal parameters of structural wooden members (structural design). The course also applies principles of material science on practical issues in wood-processing industry.
