  2. 11. Experiments, Computations and Models for Probabilistic HCF Design

    Author : Daniel Sandberg; Mårten Olsson; Gunnar Härkegård; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : High Cycle Fatigue (HCF) failure is a common failure type for many mechanical components. Traditional HCF design is based on the deterministic safety factor approach, typically used in conjunction with the point stress method. READ MORE

  4. 12. Vibration Characteristics and Structural Damping of Rotating Compressor Blades

    Author : Jia Sun; Leif Kari; Jean-François Deü; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Nowadays, the increasing demand on the high efficiency energy, low fuel consumption and environment friendly leads the turbomachinery to be operating under a critical high rotation speed at high temperature and pressure. This severe operation condition will definitely increase the probability of the occurrence of the high cycle fatigue. READ MORE

  5. 13. Modeling framework for ageing of low alloy steel

    Author : Magnus Boåsen; Pål Efsing; Jonas Faleskog; Carl F. O. Dahlberg; Christian Niordson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low alloy steel; length scale effects; size effects; plasticity; cleavage fracture; brittle fracture; weakest link; ageing; weld metal; Hållfasthetslära; Solid Mechanics;

    Abstract : Ageing of low alloy steel in nuclear applications commonly takes the form as a hardening and an embrittlement of the material. This is due to the evolution of the microstructure during irradiation and at purely thermal conditions, as a combination or separate. READ MORE

  6. 14. Modeling of structural integrity of aged low alloy steels using non-local mechanics

    Author : Magnus Boåsen; Pål Efsing; Jacques Besson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Ageing of low alloy steels affects the structural integrity assessment as it most commonly causes embrittlement and a hardening of the material. This is due to theevolution of the microstructure during operation in the specific application. READ MORE

  7. 15. Large deviation techniques applied to three questions of when

    Author : Ola Hammarlid; Anders Martin-Löf; Ingmar Kaj; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Large deviations; first passage time; stopping time; rate function; convex barrier; fallacy of large numbers; utility function; insurance; ruin; variable premium; generalized Ornstein-Uhlenbeck process; Mathematical statistics; Matematisk statistik;

    Abstract : Large deviation techniques are used to solve three problems; when is a distant convex barrier passed, when to accept a sequence of gambles and when is the time of ruin. This work is the collection of four papers. READ MORE
