Bending Properties and Vibration Characteristics of Dowel-Laminated Timber Panels Made with Short Salvaged Timber Elements

open access: yesBuildings, 2023
Salvaged timber elements often have length limitations, and therefore, their reuse in structural products normally would require additional processing and end-to-end joining.

Recognizing the future utility of a solution: When do children choose to retain and share an object to solve a future problem? [PDF]

open access: yesBr J Dev Psychol
Abstract Humans' ability to recognize the future utility of a solution is fundamental to our capacity for innovation. It motivates us to—for instance—retain and share useful tools, transforming one‐time solutions into innovations that change the future.

Influence of biological pretreatment of wooden dowels on strength of rotary welded joints

open access: yesBioResources, 2023
Welding wood achieves joints whose strength is comparable with the strength of glued joints. When welding, the top of the dowel is not welded because of the lack of melted lignin. To achieve satisfactory strength of a welded joint, it is necessary to optimize the main welding factors such as interference fit, frequency of dowel rotation, welding depth,

Experimental and Numerical Study on Shear Properties of Timber-to-timber Joint Using a Dowel Reinforced with a Self-tapping Screw

open access: yesBioResources, 2023
Herein, a beech wood dowel reinforced with a self-tapping screw (composite dowel in brief) is proposed. Composite dowels were welded into the predrilled holes by high speed rotation.

The Influence of Different Wood Modifications on Pull-out Force of Rotary Welded Dowels

open access: yesDrvna Industrija, 2023
The increasing use of modified wood justifies the intention to use it in joints made by rotary welding with dowels. Thermal modification, for example, increases the dimensional stability of wood by reducing its hygroscopicity and water absorption, but it
