  1. 1. Analysis of thermal shock in brittle materials

    Författare :Marianne Collin; KTH; []
    Nyckelord :thermal shock; thermal stress; stress intensity; vickers indentation; alumina; silicon varbide whisker reinforced alumina;

    Sammanfattning : This thesis concerns thermal shock damage of ceramicmaterials. More specifically the work is focused on theoreticaland practical aspects of a new technique for determining thethermal shock resistance of brittle materials. LÄS MER

  3. 2. Thermal shock and thermal fatigue in ceramic materials

    Författare :Tomas Andersson; KTH; []

    Sammanfattning : This thesis concerns thermal stress fracture in ceramicmaterials. The work describes a new technique for determiningthe thermal shock resistance of brittle materials as well asexperimental results and thermal stress simulations. LÄS MER

  4. 3. On dynamics and thermal radiation of imploding shock waves

    Författare :Malte Kjellander; Nicholas Apazidis; Gabi Ben-Dor; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; converging shock waves; polygonal shock waves; temperature measurments; argon; plasma creation; ionisation; spectrometry; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Converging cylindrical shock waves have been studied experimentally. Numericalcalculations based on the Euler equations and analytical comparisons basedon the approximate theory of geometrical shock dynamics have been made tocomplement the study.Shock waves with circular or polygonal shock front shapes have been createdand focused in a shock tube.
