2. 1. 3-D Forming of Paper Materials

   Author : Eric Linvill; Sören Östlund; Artem Kulachenko; Leif A. Carlsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3-D forming; finite element method; constitutive model; moisture; temperature; biaxial; hydroforming; deep drawing; 3D formning; finita elementmetoden; konstitutiv modell; fukt; temperatur; biaxiell; hydroformning; djupdragning; Hållfasthetslära; Solid Mechanics;

   Abstract : Paper materials have a long history of use as a packaging material, although traditional paper-based packaging is limited in its shape, complexity, and design. In order to better understand the deformation and failure mechanisms during 3-D forming, two experimental studies of paper materials have been conducted. READ MORE

4. 2. Material Characterization for Modelling of Sheet Metal Deformation and Failure

   Author : Stefan Marth; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

   Abstract : Weight reduction is one possibility to reduce fuel consumption and emission of transportation vehicles. Sheet metals are often used in automotive and aerospace applications and therefore the weight reduction achieved by reducing the sheet metals thickness is an important contribution to weight reduction.

5. 3. On fracture of layered materials

   Author : Jens Gunnars; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

   Abstract : This thesis is concerned with fracture in layered bimaterials. Fracture of coatings is considered to some extent. The behaviour of cracks growing normal to bimaterial interfaces is studied with the objective to clarify conditions for crack-tip shielding and amplification. READ MORE

6. 4. Modelling of Forming and Welding in Alloy 718

   Author : Lluís Pérez Caro; Mats Oldenburg; Eva-Lis Odenberger; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forming; welding; Alloy 718; damage; GISSMO; failure; Hållfasthetslära; Solid Mechanics;

   Abstract : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry due to major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the vehicle’s weight while increasing engine's efficiency. READ MORE

7. 5. On the Fracture of Thin Laminates

   Author : Sharon Kao-Walter; Blekinge Institute of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laminate; interface; crack; adhesion; crack tip driving force;

   Abstract : This thesis concerns mechanical and fracture properties of a thin aluminium foil and polymer laminate that is widely used as packaging material. The possibility of controlling the path of the growing crack propagation by adjustment of the adhesion level and the property of the polymer layer is investigated. READ MORE
