1. Fracture behaviour and related microstructures of tool steels parted-off at high rates of strain
Abstract : Increasing steel prices and environmental aspects have put forward the demand to reduce material consumption in manufacturing industry and near-net-shape manufacturing techniques have thus become increasingly important. High-velocity parting-off, or adiabatic cutting, has shown to result in very low material waste as well as narrow dimensional tolerances of parted-off samples. READ MORE

2. 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
