Outline and Purpose of the Course	Physical properties of wood depend on its directions because it is an anisotropic material. Trees evolved into a huge body as a living creature and their trunk need to support the weight of big canopy. While timber have sufficient strengths, it includes many defects such as knots. We must take it into consideration due to analyze the behavior in physical aspect. In this lecture, physical properties, theory and method of analysis and its applications techniques of wood-based materials are explained.
Course Goals	1. Understanding basic physical properties of wood. 2. Understanding theory and method on basic analysis of strength.
Schedule and Contents	1. Physical properties of wood (3) 　1.1 Several factors affecting physical properties 　1.2 Strength and size effect 　1.3 Influence of defects 2. Mechanics of materials and fracture mechanics (3) 　2.1 Introduction of mechanics of material 　2.2 Linear fracture mechanics 　2.3 Non-linear fracture mechanics 3. Analysis of strain (1) 4. Feedbak(1)
Evaluation Methods and Policy	Evaluation will be based on an overall assessment of criteria such as understanding lectures and reports or examination. Refer to '2017 Guide to Degree Programs' for attainment levels of evaluation
Course Requirements	Completion of biomaterials science is desirable. It is also desirable that students have taken introductory physics, chemistry and math course in a liberal arts program.
