  2. 6. 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.

    Author : Håkan Petersson; Robert Bjärnemo; Damien Motte; Kjell Andersson; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer-Based Design Analysis; Engineering Design process; Template; and Template-Based Design Analysis; Datorbaserad konstruktionsanalys; Konstruktionsprocess; undersökning; beräkningsstöd samt minskade ledtider; MallBaserad KonstruktionsAnalys; Computer-Based Design Analysis; Engineering Design process; Template; and Template-Based Design Analysis;

    Abstract : The current trend in industry to encourage engineering designers to take an active part in the analysis of their own design solutions is apparent in many companies today, domestically as well as abroad.From a research project with the objective to develop a computer-based design system for the design of lightweight grippers, one of the major difficulties was to overcome the system users’ lack of knowledge and experience in the design of lightweight structures and Computer-Based Design Analysis (CBDA).

  5. 8. Design Automation Systems for Production Preparation : Applied on the Rotary Draw Bending Process

    Author : Joel Johansson; Staffan Sunnersjö; Bo Bengtsson; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design automation; Rotary draw bending; Knowledge Based Engineering KBE ; and Finite Element Analysis FEA ; Other technology; Övriga teknikvetenskaper;

    Abstract : Intensive competition on the global market puts great pressure on manufacturing companies to develop and produce products that meet requirements from customers and investors. One key factor in meeting these requirements is the efficiency of the product development and the production preparation process. READ MORE

  6. 9. Microstructure and deformation behaviour of ductile iron under tensile loading

    Author : Keivan Amiri Kasvayee; Anders E.W. Jarfors; Ehsan Ghassemali; Lennart Elmquist; Kenneth Hamberg; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ductile iron; digital image correlation DIC ; in-situ tensile test; pit etching; Microscale deformation; micro-crack; finite elements analysis FEA ; cohesive elements;

    Abstract : The current thesis focuses on the deformation behaviour and strain distribution in the microstructure of ductile iron during tensile loading. Utilizing Digital Image Correlation (DIC) and in-situ tensile test under optical microscope, a method was developed to measure high resolution strain in microstructural constitutes. READ MORE
