11. Ductile Failure in High Strength Steel Sheets
Sammanfattning : Developments in computer-aided engineering and the rapid growth of computational power have made simulation-driven process and product development efficient and useful since it enables detailed evaluation of product designs and their manufacturing processes. In the context of a sheet metal component, it is vital to predict possible failure both during its forming process and its subsequent usage. LÄS MER
12. Flexible Composites - Strength, Deformation and Fracture Proecesses in Woven and D.O.S. Reinforcement Materials
Sammanfattning : In this thesis the tensile strength, deformation, damage resistance and tear propagation for flexible composites are analysed. There are two essential requirements common to all flexible composites; namely, high tearing strength and good matrix-to-fabric adhesion. The interaction of fabric and matrix is complex. LÄS MER
13. Failure of thinwalled structures under impact loading
Sammanfattning : Thinwalled structures are widely used for different applications, e.g. maritime structures,vehicles, off-shore structures, aircraft fuselage, ship panels etc., and due to their applicationthey might be exposed to high strain rate loads as blast loads. LÄS MER
14. Radiation Induced Precipitation in Reactor Pressure Vessel Steel Welds
Sammanfattning : Radiation induced clustering and precipitation affect the mechanical properties of the reactor pressure vessel (RPV) of a nuclear power plant, i.e. the material becomes embritteled. The combination of low Cu (0. LÄS MER
15. Wear of high strength steels and ductile iron and its effect on fatigue performance
Sammanfattning : Machinery components used in demanding applications are required to transmit or carry mechanical loads under severe loading conditions. They are subjected to cyclic loading and repeated sliding contact that in many cases result in a premature failure of components. LÄS MER
