  1. 1. Constitutive modelling of an additively manufactured alloy for fatigue lifing in high temperature applications

    Författare :Thomas Lindström; Daniel Leidermark; Håkan Hallberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The main objective of the work presented in this Licentiate thesis is to investigate and model the cyclic behaviour of an additively manufactured ductile nickel-based superalloy, with special emphasis on modelling the stabilised material behaviour, which is of interest for fatigue life predictions. Cyclic fatigue tests at different temperatures have been performed to investigate the cyclic mechanical behaviour of the material, where specimens built in different orientations have been used to also study the anisotropic behaviour of the material.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Low-cycle fatigue; Thermomechanical fatigue; Constitutive modelling; Anisotropy;

    Sammanfattning : This dissertation was produced at the Division of Solid Mechanics at Linköping University, and is the final result of a project that included mechanical testing and modelling of an additively manufactured ductile nickel-based superalloy.The main objective of the work presented in this thesis was to investigate and model the cyclic behaviour and the fatigue life behaviour of an additively manufactured ductile nickel-based superalloy, with emphasis on modelling the stabilised material behaviour, by which fatigue life predictions can be based upon.

  4. 3. Att skriva det grekiska : En otidsenlig position i svenskspråkig modernism

    Författare :Anders Lindström; Ulf Olsson; Thomas Götselius; Elisabeth Friis; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; the Greek; the untimely; presence; attitude; position; the tragic; myth; modernism; modernity; Lars Norén; Vilhelm Ekelund; Edith Södergran; Eyvind Johnson; Birgitta Trotzig; Literature; litteraturvetenskap;

    Sammanfattning : The aim of this thesis is to analyze how ancient Greek philosophy and literature – as it was mediated through Nietzsche – gained a vital function in the rise of early Swedish modernism and its later expressions. The turn to antiquity, within a modernism confined to the Swedish language, was not only intended as a breach in tradition, but above all to think anew, to transgress the conventions of (one’s) time.

  5. 4. A flexible real-time solution to modular design of an adaptive control system for turning

    Författare :Thomas Lundholm; Bo Lindström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turning; adaptive control; real-time control; Manufacturing engineering; Produktionsteknik;

    Sammanfattning : This thesis deals with the organization of an adaptive control system for turning and, furthermore, the development of an integration framework for subsystems in the adaptive control system. The thesis is organized in three main parts. LÄS MER
