  1. 1. Guided wave-based approach for health monitoring of composite structures; Application to wind turbine blades

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Siavash Shoja; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; structural health monitoring; composite structures; wind turbine blades; design optimization; ice detection; Guided wave propagation; numerical simulations;

    Abstract : The use of composite materials has increased in manufacturing of large structures. These structures can be subjected to different types of defects, for which detection has always been a challenge. READ MORE

  2. 2. Residual stresses and shape distortion in composite structures

    University dissertation from Luleå : Luleå tekniska universitet

    Author : J. Magnus Svanberg; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : High performance composites usually consist of continuous fibres and a thermoset matrix. One well-known example from the aerospace industry is carbon fibre epoxy composites. For that reason the manufacturing processes of thermoset composites are subject to extensive research. READ MORE

  3. 3. Prefabricated composite bridges a study of dry deck joints

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Robert Hällmark; Luleå tekniska universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture - Building engineering; Bridge construction; prefabrication; monitoring; Samhällsbyggnadsteknik och arkitektur - Byggnadsteknik; Stålbyggnad; Steel Structures;

    Abstract : This thesis deals with prefabricated composite bridges in general, and prefabricated concrete deck elements with dry joints in particular.As outlined in Paper I and Chapter 2 prefabrication has several advantages over in situ construction, and has hence been discussed for decades in the construction business.

  4. 4. Structural Composite Lithium-Ion Battery Effect of Intercalation induced volumetric changes on micro-damage

    University dissertation from Luleå : Luleå University of Technology

    Author : Johanna Xu; Luleå tekniska universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera kompositmaterial;

    Abstract : The quest for lighter materials and structures to reduce climate impacts in the automotive industry has paved the way for multifunctional solutions. Mass saving on a system level can be achieved by materials or structures having more than one primary function, thus reducing the number of components used. READ MORE

  5. 5. Industrial framework for hot-spot identification and verification in automotive composite structures

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Henrik Molker; [2019]
