2. 1. CAD-Model Parsing for Automated Design and Design Evaluation

   Author : Roland Stolt; Staffan Sunnersjö; Ola Isaksson; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design automation; CAD; KBE; Feature based modelling; Feature recognition; Product development.; Industrial engineering and economy; Industriell teknik och ekonomi;

   Abstract : Product development has both innovative and analytic sides. Starting from the requirements, a design suggestion is generated. In order to assess how well the envisioned design fulfils the requirements, it is sometimes necessary to build a computer model of it for the analysis. READ MORE

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

   Author : Roland Stolt; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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. On determining lost core viability in high-pressure die casting using Computational Continuum Mechanics

   Author : Sebastian Kohlstädt; Pär Jönsson; Julio Hernandez; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-pressure die casting; lost salt cores; computational continuum mechanics; two-phase compressible flow; OpenFOAM; CFD; fluid-structure interaction; volume-of-fluid method;

   Abstract : The subject of this thesis work is to investigate whether Computational ContinuumMechanics (CCM) can serve as a valuable tool for the casting engineerto determine a priori whether a housing concept with inlying geometries thatso far only exists in Computer Aided Design (CAD) will have the desired coolingperformance and will be manufacturable with an acceptable number ofrejects.As of spring 2019, no application in serial production of lost cores, i.

6. 4. Casting and anodising of Al alloys- Alloy design, manufacturing process and material properties

   Author : Baiwei Zhu; Caterina Zanella; Rajan Ambat; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast aluminium; Semi-solid casting; Anodising; Gjutning av aluminium; semi-solid gjutning; anodisering; komponent; gjutlegering; kisel; järn;

   Abstract : Casting and semi-solid metal (SSM) casting are widely used to manufacture near-net-shape components of Al-Si alloys in the automotive and electronic industries. In such applications, casting components need to meet the combined requirements of good mechanical properties and corrosion and wear resistance. READ MORE

7. 5. Al-7Si-Mg semi-solid castings – microstructure and mechanical properties

   Author : Jorge Santos; Anders E.W. Jarfors; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheometal™ process; semi‐solid casting; aluminium alloys; grain refinement; segregation; intermetallic phases; heat treatment; mechanical properties;

   Abstract : The vehicles industry is facing increasing demands for fuel efficiency and cost reduction due to environmental legislation, sustainability and customer demands. Therefore, there is a great need to develop and produce lightweight components by using materials and processes that offer higher specific strength and/or design optimization. READ MORE
