1. Life Prediction and Mechanical Behavior of Thermal Barrier Coatings
Abstract : Delamination and spallation of thermal barrier coating (TBC) systems, used in hot parts of gas turbines, have been studied with respect to thermal fatigue. TBCs with and without pre-existing cracks were investigated. Thermal shock tests were performed until coating spallation. READ MORE

2. Computational homogenisation and solution strategies for phase-field fracture
Abstract : The computational modelling of fracture not only provides a deep insight into the underlying mechanisms that trigger a fracture but also offers information on the post-fracture behaviour (e.g., residual strength) of engineering materials and structures. READ MORE

3. Multiscale modeling of ductile fracture in solids
Abstract : Ductile fracture occurs in many situations of engineering relevance, for example metal cutting and crashworthiness applications, where the fracture process is important to understand and predict. Increased understanding can be gained by using multiscale modeling, where the effective response of the material is computed from microscale simulations on Statistical Volume Elements (SVEs) 1 containing explicit models for the nucleation and propagation of microscopic cracks.

4. Structural Composite Lithium-Ion Battery : Effect of Intercalation induced volumetric changes on micro-damage
Abstract : The quest for lighter materials and structures to reduce climate impacts in the automotive industry has paved the way for multifunctional solutions. Mass saving on a system level can be achieved by materials or structures having more than one primary function, thus reducing the number of components used. READ MORE

5. Laboratory studies of dynamic rock fracture and in-situ measurements of cutter forces for a boring machine
Abstract : All forms of rock failure usually happen within a very wide range of loading rates covering static and dynamic loading. Since rock failure always results from fracture - the propagation of one or more cracks- the first part of the thesis is focused on laboratory studies of the influences of loading rates on rock fracture.
