  2. 1. Numerical investigation on the formation mechanism of residual stress in metal cutting

    Author : Yang Liu; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Residual stress; FEM; ; Metal cutting; Thermal-mechanical load; Plastic deformation;

    Abstract : Residual stress can be introduced unintentionally into the workpiece with various magnitudes and distributions through all manufacturing processes. These stresses have a significant effect upon the performance of the final component. READ MORE

  4. 2. Modelling and Numerical Analysis of the Centrifugal Compressor and its Operation in the Pressurised SOFC GT Process

    Author : Andre Hildebrandt; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; radial compressor; Gas Turbine; Termisk teknik; Solid Oxide Fuel Cell; termodynamik;

    Abstract : Small-scale power plants based on the SOFC-GT (Solid Oxide Fuel Cell-Gas Turbine) system are foreseen for future application such as APU units in flight transportation systems or stationary power production. Although these new systems offer high load flexibility and potentially high efficiency, there are several constraints referring to thermal/mechanical stress of the fuel cell as well as to a potential risk of aerodynamic instability of the GT compressor due to the different physical behavior of the SOFC and the GT.

  5. 3. Static and Fatigue Failure of Bolted Joints in Hybrid Composite-Aluminium Aircraft Structures

    Author : Zlatan Kapidzic; Hans Ansell; Kjell Simonsson; Larsgunnar Nilsson; Michael Wisnom; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid structures; Composites; Bearing failure; Bolted joints;

    Abstract : The use of fibre composites in the design of load carrying aircraft structures has been increasing over the last few decades. At the same time, aluminium alloys are still present in many structural parts, which has led to an increase of the number of hybrid composite-aluminium structures. READ MORE
