  3. 12. Application of cohesive modeling in joining technology

    Författare :Saeed Salimi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rivet joints; mixed-mode cohesive failure; mixed material; J-integral; Thick adhesive layer;

    Sammanfattning : ABSTRACTThis thesis summarizes the development of cohesive modeling of joints. It presents some new developments regarding the effects of non-zero thickness of adhesive layers and a novel approach of using the concept of cohesive modeling to characterize the failure behavior of rivet joints.

  4. 13. Growth of fatigue cracks subjected to non-proportional Mode I and II

    Författare :Peter Dahlin; Mårten Olsson; Veronique École; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue crack growth; Mode II overloading; Crack closure; Sequential mixed mode loading; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : This thesis deals with some aspects of crack growth in the presence of cyclic loading, i.e. fatigue. The cyclic load cases studied here are primary of non-proportional mixed mode type. LÄS MER

  5. 14. On the cost-efficiency of probability sampling based mail surveys with a web response option

    Författare :Peter Werner; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : Web surveys - the collection of survey data by means of self-administered questionnaires on the Internet - are becoming increasingly popular, perhaps mostly because of advantageous cost factors. If e-mail contacts are used, the cost benefit of a Web survey, compared with a mail or telephone survey, could be major. LÄS MER

  7. 15. Flexible cables for massive-parallel high-speed data communications

    Författare :Allan Huynh; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The demand for high-speed data communications has pushed both the wired and wireless technologies to operate at higher and higher frequencies. Classic Kirchhoffs voltage and current laws cannot be directly applied, when entering the microwave spectrum for frequency > 1 GHz. Instead, the transmission line theory should be used. LÄS MER
