  3. 3. Finite element modelling of the mechanics of solid foam materials

    Författare :Steven Ribeiro-Ayeh; Dan Zenkert; Andrew M. Kraynic; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering design; point-stress criterion; bi-material interface; foam; cellular sollid; micro-mechanical modelling; Konstruktionsteknik; Construction engineering; Konstruktionsteknik;

    Sammanfattning : Failure of bi-material interfaces is studied with the aim to quantify the influence of the induced stress concentrations on the strength of the interfaces. A simple point-stress criterion, used in conjunction with finite element calculations, is evaluated to provide strength predictions for bi-material bonded joints and inserts in polymer foam. LÄS MER

  4. 4. Micro-mechanical FE-simulations of the plastic behaviour of steels undergoing martensitic transformation

    Författare :Kjell Simonsson; Sören Sjöström; Marcel Berveiller; Linköpings universitet; []
    Nyckelord :Steel; martensitic transformation; grain constitution; finite element simulations; plastic behaviour; transformation kinetics; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis is concerned with the mechanical behaviour of steels undergoing martensitic transformation. More specifically, the aim has been to develop a method to numerically stimulate the mean strain (or stress) response associated with a prescribed temperature and mean stress (or strain) variation.

  5. 5. Evaluation of Low Temperature Damage in Asphalt Mixtures with Non-Contact Resonance Testing

    Författare :Abiy Bekele; Denis Jelagin; William Buttlar; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt concrete; dynamic modulus; non-contact excitation; resonance testing; thermally induced damage; viscoelasticity; Asfaltbetong; beröringsfri excitation; resonansfrekvens; resonansprovning; styvhetsmodul; Building Materials; Byggnadsmaterial;

    Sammanfattning : Thetemperature induceddamage in asphalt mixtureshas always been a major distress that requires a substantialconsiderationin the asphalt industry. One of the most important aspects of studying temperature induceddamage is developing a practical test method for evaluation of the material’s resistanceto it. LÄS MER
