4. 12. Deformation and Fatigue Behaviour of Aluminium Alloys for High Specific Power IC Engine Applications

   Author : Elanghovan Natesan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cylinder head; aluminium; constitutive models; thermo-mechanical fatigue; fatigue; ageing; mechanical behaviour; A356;

   Abstract : The development towards higher specific power and lower displacement engines in recent years has placed increasingly high thermal loads on the internal combustion engine materials. Further, the advent of hybrid power trains placing higher demands on quick starts and a rapid approach to maximum power necessitates the automotive industry to move towards a more robust computational thermo-mechanical fatigue life prediction methodology to develop reliable engines and reduce developmental costs.

5. 13. Calcium aluminate cement as dental restorative : Mechanical properties and clinical durability

   Author : Karin Sunnegårdh-Grönberg; Jan van Dijken; Preben Hørsted Bindslev; Umeå universitet; []
   Keywords : mechanical properties; clinical; restorations; ceramic; cement; resin composite; adaptation; SEM; odontologi; Odontology;

   Abstract : In 1995, the Swedish government recommended the discontinuation of amalgam as restorative in paediatric dentistry. Because the mercury content in amalgam constitutes an environmental hazard, its use has declined. READ MORE

6. 14. Machining properties of wood : Tool wear, cutting force and tensioning of blades

   Author : Luis Cristovao; Frieder Scholz; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Abstract : Cutting processes, in general, and wood cutting processes, in particular, are complex to explain and describe with many influencing factors. Wood, in contrast to man-made fabricated materials, is not a homogenous and distinct material, but a multifaceted and nonhomogeneous biological material. READ MORE

7. 15. Mechanical Properties of Resistance Spot Welds in Lightweight Applications

   Author : Davood Afshari; Zuheir Barsoum; Arne Melander; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spot Weld; Aluminum alloy; Mechanical Properties; Finite Element; SRA - Production; SRA - Produktion;

   Abstract : This licentiate thesis is concerned with residual stresses in aluminum alloy 6061-T6 resistance spot welded joint. Several topics related to mechanical strength of welded structures are treated such as; nugget size and microhardness and microstructures of weld zone and their influence on mechanical strength of welded structure, failure load measurement using tensile-shear test, resistance spot welding simulation, residual stress measurement by X-ray diffraction method and analysis effect of welding parameters on the mechanical strength and the residual stresses.
