   Abstract : Birch (Betula spp.) is a hardwood species with a wide natural distribution on the Eurasian continent, especially in northern Europe. READ MORE

4. 2. In-plane mechanical properties of acetylated birch plywood and its response to humidity elevation

   Author : Yue Wang; Magnus Wålinder; Roberto Crocetti; Marie Johansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Birch plywood; wood modification; acetylation; in-plane mechanical properties; load-to-face grain angle; moisture effect; Björkplywood; trämodifiering; acetylering; mekaniska egenskaper i planet; belastningsriktning; klimategenskaper; Building Materials; Byggnadsmaterial;

   Abstract : Due to the recent flourish of modern timber structures, there is an increasing demand for engineered wood products (EWPs). However, outdoor exposure of EWPs often poses a risk of durability-related issues. READ MORE

5. 3. On the in-plane mechanical properties of birch plywood

   Author : Tianxiang Wang; Magnus Wålinder; Roberto Crocetti; Bo Källsner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Birch plywood; in-plane mechanical properties; load-to-face grain angle; failure criteria; size effect; moisture; Björkplywood; mekaniska egenskaper i planet; belastningsvinkel relativt ytfaneren; brott kriterier; storlekseffekt; fukt; Building Materials; Byggnadsmaterial;

   Abstract : Birch plywood has favorable mechanical properties that could be used in new types of connections for timber structures, and thus enable a substitution of the current system with steel plates. Such new connections could result in significant advantages in terms of environmental impact and economy as well as ease of prefabrication and mountability. READ MORE

6. 4. Deformation and Fracture Behavior of Transparent Wood-Polymer Biocomposites

   Author : Erik Jungstedt; Lars Berglund; Sören Östlund; Bent Sørensen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; fracture mechanics; strain field measurement; cohesive zone modeling; mechanical properties; Solid Mechanics; Hållfasthetslära;

   Abstract : Transparent wood-polymer biocomposites (TWPBs) are interesting wood-based materials with a unique combination of optical transmittance and mechanical properties. The wood substrate is delignified (removal of lignin) while the wood microstructure is preserved. READ MORE

7. 5. On the relation between paperboard properties and packaging performance

   Author : Gustav Marin; Sören Östlund; Mikael Nygårds; Christer Korin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

   Abstract : Paper-based materials, such as paperboard, are commonly used as packaging materials. Inaddition to the advantage that wood as a raw material is renewable, there are also many otherbenefits of paperboard. READ MORE
