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

    Författare :Steven Ribeiro-Ayeh; Dan Zenkert; Andrew M. Kraynic; KTH; []
    Nyckelord :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

  5. 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.

  7. 5. Understanding Adhesive Mixtures for Inhalation : Particle Dynamics Modelling and Segregation Experiments

    Författare :Sohan Sarangi; Göran Frenning; Göran Alderborn; Kyrre Thalberg; Johannes Khinast; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inhalation; adhesive mixtures; dry powder inhaler; discrete element method; segregation; stability; modeling; Galenisk farmaci; Pharmaceutics; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Pulmonary route has been used as a source of drug delivery to lungs for centuries. Drugformulation decides the type of inhaler devices such as pressurized metered-dose inhalers(pMDIs), nebulizers and dry powder inhalers (DPIs). LÄS MER
