| Outline and Purpose of the Course |
The role of wood as a carbon-neutral and sustainable resource is expected to become more significant in the future. Although it has been a familiar and well-known material for a long time, it is necessary to fully understand its properties to comprehensively demonstrate its performance. This course focuses on the physical properties of wood and explains the theories that must be understood when using it as a material. |
|||
| Course Goals |
・One of the features of wood, apart from its strength and workability, is that it is a hygroscopic material. To understand the mechanism and theories of its moisture absorption and release. ・Wood is a viscoelastic body having not only elastic properties but also viscous properties. To understand the properties of viscosity and how to analyze it . ・To know how to measure various physical properties |
