3. 27. Deformation and Fatigue Behaviour of Aluminium Alloys for High Specific Power IC Engine Applications

   Författare :Elanghovan Natesan; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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.

4. 28. Influences of temperature, fatigue and mixed mode loading on the cohesive properties of adhesive layers

   Författare :Tomas Walander; Christian Berggreen; Högskolan i Skövde; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; cohesive law; fatigue; finite element analysis; fracture energy; mixed mode; multi-axial fatigue; potential model; temperature; Mechanics of Materials; Materialmekanik;

   Sammanfattning : This thesis concerns some aspects that have influence on the strength of adhesive layers. The strength is determined by the stress deformation-relation of the layer. This relation is also referred to as cohesive law. LÄS MER

5. 29. Fatigue in patients with chronic heart failure. Patient experience and consequences of fatigue in daily life

   Författare :Kristin Falk; Göteborgs universitet; []
   Nyckelord :fatigue; chronic heart failure; uncertainty; sense of coherence; anxiety; depression; symptom distress; hemoglobin; functional status;

   Sammanfattning : Although fatigue is a prevalent and distressing symptom in patients with chronic heart failure (CHF), it is an underestimated problem in the care of patients, and consequently, insufficiently investigated. The primary aim of this thesis was, therefore, to advance the knowledge from the patients? perspective by describing characteristics of the fatigue experience and its consequences in daily life in patients with CHF.

7. 30. Residual Stress Analysis and Fatigue of Welded Structures

   Författare :Zuheir Barsoum; Jack Samuelsson; Jan Langkjear Hansen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; welding; fatigue; finite element analysis; fracture mechanics; residual stresses; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : This licentiate thesis is generally concerned with the fatigue of welded structures. Several topics related to fatigue of welded structures are treated such as; weld defects and their influence on fatigue performance of welded structures, fatigue life prediction using LEFM (Linear Elastic Fracture Mechanics), fatigue testing, welding simulation, residual stress prediction and measurement and their influence on fatigue.
