  1. 1. Very high cycle fatigue of high performance steels

    Detta är en avhandling från Karlstad : Karlstad University

    Författare :Vitaliy Kazymyrovych; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatigue; tool steels; ultrasonic testing; fatigue life; crack growth rate; fatigue mechanisms; Materialteknik; Materials Engineering;

    Sammanfattning : Many engineering components reach a finite fatigue life well above 109 load cycles. Some examples of such components are found in airplanes, automobiles or high speed trains. For some materials the fatigue failures have lately been found to occur well after 107 load cycles, namely in the Very High Cycle Fatigue (VHCF) range. LÄS MER

  2. 2. Fatigue och återhämtning efter hjärtinfarkt

    Detta är en avhandling från Göteborg : Institutionen för vårdvetenskap och hälsa vid Sahlgrenska akademin, Göteborgs universitet

    Författare :Ulla Fredriksson-Larsson; Eva Brink; Pia Alsén; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coping strategies; fatigue; grounded theory; myocardial infarction; nursing; person-centeredness; psychometric evaluation; Rasch analysis; stress; symptom assessment; symptom experience; symptom research; The Multidimensional Fatigue Inventory-20 MFI-20 ; Vårdvetenskap; Nursing science;

    Sammanfattning : Fast and efficient acute medical treatment of myocardial infarction (MI) has developed during recent years and has resulted in a reduced number of days spent in hospital and increased survival. To optimize persons’ recovery, secondary preventive strategies are important. LÄS MER

  4. 4. Fatigue strength of engineering materials the influence of environment and porosity

    Detta är en avhandling från Stockholm : KTH

    Författare :Jan Linder; Bengt Lindberg; Lennart Josefsson; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; cast aluminium; hardened steels; fatigue; corrosion; crack propagation; spot weld; porosity; TECHNOLOGY Materials science Other materials science; TEKNIKVETENSKAP Teknisk materialvetenskap Övrig teknisk materialvetenskap;

    Sammanfattning : The objective of this work was to use LEFM in order to assess the detrimental influence of surrounding chloride-containing environments for stainless steels, hardened steel as well as for a cast aluminium alloy. An additional aim was also to use LEFM to assess the influence of porosity on the fatigue properties for different commercial cast aluminium alloys and manufacturing methods. LÄS MER

  5. 5. Fatigue after traumatic brain injury exploring novel methods for diagnosis and treatment

    Detta är en avhandling från Umeå : Umeå University

    Författare :Nils Berginström; Anna Nordström; Peter Nordström; Lars Nyberg; Jan Lexell; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; fatigue; OSU6162; randomized clinical trials; functional magnetic resonance imaging; neuropsychology; structural magnetic resonance imaging; white matter hyperintensities; rehabiliteringsmedicin; Rehabilitation Medicine;

    Sammanfattning : Background: Traumatic brain injury (TBI) is one of the most common causes of disability and mortality. While some patients recover quickly, especially at the mild side of the injury severity continuum, many will experience symptoms for years to come. LÄS MER
