  1. 11. Numerical simulation of crack growth and wear in rails

    Författare :Jim Brouzoulis; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crack propagation; material forces; Rolling Contact Fatigue; wear; railway mechanics;

    Sammanfattning : Wear and rolling contact fatigue (RCF) of rails are huge problems for the railway industry with increased world-wide occurrence during the last decades. It is, therefore, of high interest to develop tools for the prediction of wear and RCF which can be used to estimate rail life. LÄS MER

  3. 12. Development of Energy-based Damage and Plasticity Models for Asphalt Concrete Mixtures

    Författare :Ibrahim Onifade; Björn Birgisson; Linbing Wang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-based models; damage; X-ray computed tomography; continuum plasticity mechanics CPM; effective micro-crack stress; Transportvetenskap; Transport Science;

    Sammanfattning : Characterizing the full range of damage and plastic behaviour of asphalt mixtures under varying strain-rates and stress states is a complex and challenging task. One reason for this  is partly due to the strain rate and temperature dependent nature of the material as well as the variation in the properties of the constituent materials that make up the composite asphalt mixture.

  4. 13. A Theoretical Study of Carbon Nanotubes in Electronic Packaging Applications

    Författare :Zhili Hu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; simulation; thermal interface material; continuum; electronic packaging; MDs; CNT;

    Sammanfattning : The continuous decrease in size of transistors has allowed more components to be integrated in a single unit area and brings a range of opportunities as well as problems to the electronic packaging industry. To meet these challenges, the introduction of Carbon Nanotubes (CNT), which display a series of extraordinary properties, have attracted great interest. LÄS MER
