  2. 1. Finite Element Analysis and Design of Experiments in Engineering Design

    Author : Martin Eriksson; Innovation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element analyses; Predictive Design Analysis; Mechanical engineering design process; Design Of Experiments; Predictive Engineering;

    Abstract : Projects with the objective of introducing Finite Element Analysis (FEA) into the early phases of the design process have previously been carried out at the Department of Machine Design, see e.g. the Doctoral thesis by Burman [13]. These works clearly highlight the usefulness of introducing design analysis early in the design process. READ MORE

  4. 2. From CAD to FEA : A design automation perspective

    Author : Roland Stolt; Jönköping University; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Idealisation; CAD; Finite element analysis; mid-surfaces; KBES; Feature based modelling; knowledge based systems; TECHNOLOGY; TEKNIKVETENSKAP; Construction engineering; Konstruktionsteknik;

    Abstract : CAD-models of parts produced by injection moulding or die-casting are often complex making the task of automated geometrical idealisation for finite element analysis difficult. Conventional tools for geometric idealisation are not ideal for the task, as will be shown in the thesis. READ MORE

  5. 3. Template-Based Design Analysis : An Alternative Approach for the Engineering Designer to Perform Computer-Based Design Analysis

    Author : Håkan Petersson; Robert Bjärnemo; Damien Motte; Kjell Andersson; Högskolan i Halmstad; []

    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).

    Abstract : This thesis focuses on the effect of microstructural variation on the mechanical properties and deformation behavior of ductile iron. To research and determine these effects, two grades of ductile iron, (i) GJS-500-7 and (ii) high silicon GJS-500-14, were cast in a geometry containing several plates with different section thicknesses in order to produce microstructural variation.
