2. 1. Numerical Modelling and Analysis of Orthogonal Metal Cutting

   Author : Mathias Agmell; Industriell Produktion; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal Cutting; Finite Element Method; Deformation Zones; Sub-surface Deformation; Tool Stress; Inverse Analysis; Kalman Filter; Minimum Chip Thickness;

   Abstract : Most components in use in our society have undergone a machining process at some stage within its manufacturing cycle. As a result, the economics of the machining process plays an important role in the manufacturing costs. READ MORE

4. 2. Tool steel for tool holder applications : microstructure and mechanical properties

   Author : Anna Medvedeva; Jens Bergström; Birger Karlsson; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steel; tool holder; microstructure; mechanical properties; machinability; Materials science; Teknisk materialvetenskap;

   Abstract : Large improvements in cutting tool design and technology, including the application of advanced surface engineering treatments on the cemented carbide insert, have been achieved in the last decades to enhance tool performance. However, the problem of improving the tool body material is not adequately studied. READ MORE

5. 3. Proteomic Analysis of Peroxisomal Proteins

   Author : Jia Mi; Susana Cristobal; Bettina Warscheid; Uppsala universitet; []
   Keywords : Cell and molecular biology; peroxisome; proteomics; biomarker; aging; pollution assessment; Cell- och molekylärbiologi;

   Abstract : Peroxisome is a ubiquitous eukaryotic organelle with a single-layer membrane. It maintains various functions that differ depending on the species and cell types, as well as the environmental or developmental conditions. READ MORE

6. 4. Tolerance Analysis Framework for Cutting Tool Interface Design

   Author : Soner Camuz; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Variation simulation; reliability-based optimization; tolerance analysis; cutting tool interface design; geometry assurance;

   Abstract : Tolerance analysis of cutting tool interface designs is a field with many opportunities for further development of existing methodologies. Cutting tool interface designs require multiple contacting surfaces, allocating the stress generated from the cutting forces, to avoid excessive deformation of the interface. READ MORE

7. 5. Moisture-induced stress and distortion of wood : A numerical and experimental study of wood's drying and long-term behaviour

   Author : Sara Florisson; Sigurdur Ormarsson; Johan Vessby; Kent Persson; Linnéuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analytical method; calibration; controlled climate; creep; distortion; experimental methodology; FEM; fibre orientation; mechano-sorption; moisture transport; natural climate; Norway spruce; numerical model; three-dimensional; timber beam; validation; wood; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

   Abstract : With the current advances made in three-dimensional modelling of wood, it is possible to provide an overall picture of moisture flow, and moisture-induced stress and deformations, whereas previously, experiments only provided local measurements. The main aim of the doctoral thesis is to investigate the possibilities of the developed three-dimensional numerical model to predict the behaviour of wood when simultaneously exposed to a mechanical load and a particular climate.
