1. 21. Cost and weight effective composite design of automotive body structures

   Författare :Per Mårtensson; Dan Zenkert; Malin Åkermo; Lars Nyborg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : The automotive industry stands in front of a great challenge, to decrease its impact on the environment. One important part in succeeding with this is to decrease the structural weight of the body structure and by that the fuel consumption or the required battery power. LÄS MER

3. 22. Technical cost modelling and efficient design of lightweight composites in structural applications

   Författare :Mathilda Karlsson Hagnell; Malin Åkermo; Dan Zenkert; Gerhard Ziegmann; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technical cost modelling; composite materials; carbon fibre; lightweight design; optimization; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : A lightweight transport design reduces fuel costs and emissions and can be achieved through the use of fibre-reinforced composite materials. Although lightweight, the composite raw material can be expensive and the sequential component production challenging and costly. LÄS MER

4. 23. New Perspectives on Analysis and Design of High-Speed Craft with Respect to Slamming

   Författare :Mikael Razola; Anders Rosén; Ermina Begovic; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slamming; high-speed craft; finite-element analysis; design methods; experimental analysis; numerical simulations; design loads; statistical analysis; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : High-speed craft are in high demand in the maritime industry, for example, in maintenance operations for offshore structures, for search and rescue, for patrolling operations, or as leisure craft to deliver speed and excitement. Design and operation of high-speed craft are often governed by the hydrodynamic phenomena of slamming, which occur when the craft impact the wave surface. LÄS MER

5. 24. Modelling the viscoplastic properties of carbon black filled rubber : A finite strain material model suitable for Finite Element Analysis

   Författare :Rickard Österlöf; Leif Kari; Alan Muhr; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcing fillers; rubber; finite strain; viscoplastic; förstärkande fyllmedel; gummi; finita töjningar; viskoplastisk; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : An increased environmental awareness, legal demands and the large part of total costs attributable to fuel cost are all incentives for the automotive industry to reduce fuel consumption. The optimal driveline to enable this reduction depends on the operational conditions and the available infrastructure. LÄS MER

7. 25. Fatigue and Fracture of High-Strength Steels : Improving Reliability in Strength Assessment

   Författare :Gustav Hultgren; Zuheir Barsoum; Rami Mansour; Torbjörn Narström; Gary Marquis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-Strength Steel; Quality assurance; Probabilistic modeling; Fatigue; Fracture mechanics; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : Structural steel plays a fundamental role in the heavy industry, serving as a key material for numerous load-bearing products and equipment. Its widespread use is attributed to its robustness, resistance to wear, ease of use in construction, and cost-effectiveness. LÄS MER
