1. 1. In-Plane Fracture of Paper

   Författare :Johan Tryding; Institutionen för byggvetenskaper; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Paper; Fracture energy; Strain softening; Localized damage; Fracture mechanics;

   Sammanfattning : The in-plane failure of paper is studied in this work by means of a cohesive crack model from experimental as well as theoretical perspectives. Localized damage at in-plane tension of short paper strips is studied for low strain rates. LÄS MER

3. 2. Strength of Sandwich Panels Loaded in In-plane Compression

   Författare :Anders Lindström; Dan Zenkert; Stefan Hallström; Per-Lennart Larsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sandwich; in-plane compression; energy absorption; debond; postbuckling; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : The use of composite materials in vehicle structures could reduce the weight and thereby the fuel consumption of vehicles. As the road safety of the vehicles must be ensured, it is vital that the energy absorbing capability of the composite materials are similar to or better than the commonly used steel structures.

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

   Författare :Tianxiang Wang; Magnus Wålinder; Roberto Crocetti; Bo Källsner; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 4. In-plane tension behaviour of masonry

   Författare :Miklos Molnar; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; restrained shrinkage; cracking; movement joints; Building construction; mortar joints; KstrMasonry; masonry; in-plane tension; Byggnadsteknik; murverk; sprickor; krympning; dilatationsfogar;

   Sammanfattning : The main purpose of the present work is to increase knowledge of in-plane tension behav-iour of masonry and develop a model able to describe the impact of parameters influencing cracking caused by restrained shrinkage. In the process the mechanism of load transfer between units and mortar joints is described. LÄS MER

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

   Författare :Yue Wang; Magnus Wålinder; Roberto Crocetti; Marie Johansson; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
