   Abstract : The pulp- and paper industry is a key industry globally and stands for a production of 600 million tonnes pulp and paper worldwide with a total revenue of 400 billion dollars. Due to high quality requirements on paper, it is important to use instruments that control that the produced paper fulfill the promised requirements. READ MORE

4. 3. A SIMULATION WITH FINITE ELEMENTS TO MODEL STEEL SHEET SLITTING : A Master Thesis in Engineering Physics

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Adam Ahlgren Peters; [2019]
   Keywords : Finite element Method; steel; steel shearing; high performance steels; Finita Element Metoden; FEM; stål; stålklippning; höghållfasta stål; industriell ståltillverkning; spaltning;

   Abstract : A steel slitting process is simulated using FEM (Finite Element Method) in order to see potential defects along the edge in a steel sheet after it has been cut. The model's results were compared to microscope images of the steel sheet in order to verify accuracy. READ MORE

5. 4. Methods to create compressive stress in high strength steel components

   University essay from

   Author : Amir Abdin; Kaveh Feyzabi; Oskar Hellman; Henrietta Nordström; Dilman Rasa; Gustav Thaung Tolförs; Per-Olof Öqvist; [2018]
   Keywords : residual compressive stress; high strength steel; methods of inducing stress; analyzing stress;

   Abstract : Residual compressive stresses can be used to increase the lifetime of parts under cyclic stress as they negate the applied tensile stresses that cause crack initiation and propagation in the material. The goal of this project was to investigate methods to induce stresses, their advantages and disadvantages as well as depth and magnitude of induced stresses, and also to find methods of analyzing the induced residual stresses.

6. 5. Sharp Edge Cutting through Paperboard

   University essay from Lunds universitet/Hållfasthetslära

   Author : Daniel Jern; August Leek; [2017]
   Keywords : Slitting; Cutting; Fracture mechanics; Fracture modelling; Crack propagation modelling; Paperboard modelling; Technology and Engineering;

   Abstract : The aim of this thesis is to investigate the micro mechanical damage and the failure of paperboard during sharp edge cutting. Tetra Pak is at the very forefront of the food packaging industry and in order to keep this market position, continuous improvements are of great importance. READ MORE
