Understanding the properties of wood, Professor Jim Woodhouse, January 5, 2024

The talk will look at the properties of wood that determine its vibration behavior: density, various stiffnesses, and damping. All these properties are determined by the pattern of the cell structure. We will start with microscope images and then use those to motivate simple mechanical models which explain, for example, why the long-grain stiffness of spruce is so much higher than the cross-grain stiffness. We will look at how the properties of a cut plate depend on the cutting angles: the two key angles describe “grain runout” and “off the quarter”. Finally, we will look at ways to measure wood properties - both hi-tech and lo-tech approaches 00:00 Professor Jim Woodhouse 54:19 Questions and Discussions
