2. 11. In-Plane Fracture of Paper

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

   Abstract : 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. READ MORE

4. 12. Modelling Fiber Network Materials:Micromechanics, Constitutive Behaviour and AI

   Abstract : This thesis focuses on understanding the mechanical behavior of fiber-based materials by utilizing various modeling approaches. Particular emphasis is placed on their structural variability, anisotropic properties, and damage behavior. READ MORE

5. 13. Mechanics of Paperboard Packages : Performance at Short Term Static Loading

   Author : Liliana Beldie; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Paper 1Several problems emerge when a paperboard package is modeled by means of the nite element method. One of the issues that one has to deal with is the constitutive model of the paperboard. Paperboard and paper in general areorthotropic materials, which means that constitutive parameters in three orthogonal directions must be determined. READ MORE

6. 14. Mechanics of Nanocellulose Foams : Experimental and Numerical Studies

   Author : Prashanth Srinivasa; Artem Kulachenko; Laurent Orgéas; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

   Abstract : Nanofibrillär cellulosa (NFC) skum är en intressant klass av cellulära material med möjliga applikationer som sträcker sig från fordonsindustrin till biomedicin då det har unika och önskvärda mekaniska egenskaper. I ljuset av de senaste framstegen inom framställning av skum förutspås det tillämpas inom en rad olika områden, inklusive områden där dess mekaniska egenskaper är viktiga. READ MORE

7. 15. Numerical homogenization of network models and micro-mechanical simulation of paperboard

   Author : Morgan Görtz; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; domain decomposition; paper model; local orthogonal decomposition; Bending; paper simulation; network model; multiscale;

   Abstract : Micro-mechanical simulations of paper products involve complex geometries and challenging numerical problems. This work considers micro-mechanical simulations where individual paper fibers are modeled and resolved. This level of detail is useful in paper-product development, where wood composition and other fiber-based parameters are essential. READ MORE
