1. Microstructural Evolution In As-cast Alloys during Plastic Deformation
Abstract : The effect of deformation on microstructural changes in metals and alloys is the subject of considerable practical interest. The ultimate goal is to control, improve and optimize the microstructure and texture of the finished products produced by metal forming operations. READ MORE

3. Microstructural changes in high strength steels exposed to large deformation and high strain rates
Abstract : Increasing steel prices and environmental aspects have put forward the demand to reduce material consumption and energy usage in manufacturing industry and near-net-shape manufacturing techniques have thus become increasingly important. High-velocity parting-off,high-velocity forming and cold ring rolling are three such manufacturing methods that exhibit great potentials in terms of material waste reduction. READ MORE

4. On the Modeling of Porous Media with Emphasis on Localization
Abstract : The mechanics of porous media is nowadays relevant in a broad spectrum of engineering applications. In the case of geomaterials, the description of the mechanical behavior is complicated by the fact that the deformation characteristics involve (strain) localization, which is indeed the main topic of this thesis.

5. Mechanical Properties and Deformation Behaviour of Polymer Materials during Nanosectioning : Characterisation and Modelling
Abstract : Research in local fracture processes and micro-machining of polymers and polymer-based composites has attracted increasing attention, in development of composite materials and miniaturisation of polymer components. In this thesis, sectioning (machining) of a glassy polymer and a carbon nanotube based composite at the nanoscale was performed by an instrumented ultramicrotome. READ MORE
