  2. 1. Towards Changeability Quantification for Product-Service Systems Design

    Author : Raj Jiten Machchhar; Alessandro Bertoni; Johan Wall; Fredrik Elgh; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Changeability quantification; early design; Uncertainty; Value robustness; Operational Scenario; Product-Service Systems; Systems Engineering.; Maskinteknik; Mechanical Engineering;

    Abstract : Tough competition and volatile global markets have pushed the manufacturing industries to develop solutions more customer-centric with optimal utilization of resources. One of the key reasons behind developing a customer-centric solution is the increased customer value that imparts a competitive edge to the manufacturing industries, eventually leading them to sustain their businesses.

  4. 2. Microstructure-based Mechanical Behaviour in Structural Analyses of Cast Components

    Author : Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Torsten Sjögren; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Component behaviour; Structural analysis; Mechanical behaviour; Casting process simulation; Finite element method simulation;

    Abstract : In the process of developing cast iron and cast aluminium components, the co-operation between product development and production is important. On the engineering level, this co-operation is limited already in the product development phase e.g. by the lack of established methods to consider the mechanical behaviour of the completed component.

  5. 3. On core and bi-layered all-ceramic fixed dental prostheses, design and mechanical properties : studies on stabilized zirconiumdioxide

    Author : Deyar Mahmood Jallal Hadi; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Y-TZP; Zirconia; All-ceramic FDPs; connector design; radius; state-of-the-art; CAD CAM; multi-layer technique; veneering ceramic; split-file; over-pressing; dental porcelain; MECHANICAL PROPERTIES;

    Abstract : Loss of teeth can affect a person’s self-esteem, social life, appearance and oral function. Reconstruction of a missing tooth has scientifically been shown to increase self-esteem and quality of life and to maintain oral function. For many patients a fixed dental prostheses (FDP) is preferred, either tooth- or implant-supported. READ MORE

  6. 4. The influence of microstructure on mechanical and tribological properties of lamellar and compacted irons in engine applications

    Author : Rohollah Ghasemi; Anders E. W. Jarfors; Ricardo César Dommarco; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; Si solution-strengthened CGI; microstructure; mechanical properties; modelling and simulation; tribology; abrasive wear; scratch testing;

    Abstract : Lamellar graphite iron (LGI) is commonly used in diesel engine applications such as piston rings–cylinder liner where an excellent combination of physical and tribological properties is essential to avoid scuffing and bore polishing issues. The excellent tribological behaviour of LGI alloys is related to the graphite lamellas, which act as solid lubricant agents by feeding onto the tribosurfaces under sliding conditions. READ MORE

  7. 5. On Energy Efficient Mobile Hydraulic Systems : with Focus on Linear Actuation

    Author : Kim Heybroek; Petter Krus; Jan-Ove Palmberg; Torben Ole Andersen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this dissertation, energy efficient hydraulic systems are studied. The research focuses on solutions for linear actuators in mobile applications, with emphasis on construction machines. Alongside the aspect of energy efficiency, the thesis deals with competing aspects in hydraulic system design found in the development of construction machines. READ MORE
