Wood grain is the arrangement of fibers inside a tree, laid down ring by ring over the life of the trunk. When a log is sawn, that internal structure becomes the visible pattern of lighter and darker bands on every board. The pattern changes how the board takes stain, how it moves with moisture, and […] The post Understanding Wood Grain: Types, Patterns, and How It Affects Strength appeared first…
Images of the benches at New York City's High Line Park spread around the world when the project opened in 2009. Emerging diagonally from the same material and modular pattern as the paving, they transition seamlessly from concrete to wood, evoking the railway tracks that once occupied the site. To withstand decades of exposure to the elements, the project required a wood species of exceptional d…
We committed ourselves to measure the fracture toughness of lime wood in a wide range of relative humidities (RH). Thanks to those experiments, we will better answer the question of what threatens wooden sculptures in historic interiors where climate fluctuations reach such extremes. The samples were stabilized for weeks in sealed containers where the RH READ MORE
We started laboratory measurements of the mechanical properties of lime wood. Check out the photo report of our first attempts and small successes (the crack growth takes place where expected!) The research is a part of the Preludium 19 project, project number 2020/37/N/HS2/01727/2, financed by the National Science Center, Poland.
