1. On indentation methods for characterization of inelastic materials
Sammanfattning : .... LÄS MER
2. Analysis of thermal shock in brittle materials
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. Relaxation and nanomechanical studies of the vickers residual stress field in glass
Sammanfattning : The Vickers residual stress field (VRSF) in soda-lime glass results from the elastic-plastic contact event that takes place when a Vickers diamond pyramid is loaded onto the surface of the material in an indentation cycle. The importance of elastic-plastic indentation lies in the contact damage that it gives rise to in the surface of the glass. LÄS MER
4. Spark Plasma Sintered 3Y-TZP/CNT composites
Sammanfattning : Composites of 3 mol% yttria-doped tetragonal zirconia (3Y-TZP) reinforced with multiwalled carbon nanotubes (MWCNT) up to 2 wt% have been produced using spark plasma sintering (SPS). The theoretical densities of the studied composites were found to be between 99.4 and 97.4 %. LÄS MER
5. Thermal shock and thermal fatigue in ceramic materials
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
