1. Study of precipitation in martensitic Fe-C-Cr alloys during tempering : Experiments and modelling
Abstract : Understanding the precipitation reaction is very important since precipitation hardening is one of the most effective strengthening mechanisms in metallic alloys. In martensitic steels, a tempering heat treatment is often performed. READ MORE

2. Determination of Material Properties for Fire Modelling
Abstract : Fire and flame spread are very complex phenomenon to study. Several aspects need to be considered and treated. In order to be able to do a correct analysis of the flame spread phenomenon, which is necessary to be able to predict flame spread, knowledge of material properties are needed. Material properties can be obtained in different ways. READ MORE

3. Modelling of Granular Materials
Abstract : The aim of this doctoral study is to develop and implement a material model for granular materials. The course of this work was concentrated upon a non-associated plasticity model with yield surface and the flow potential expressed in terms of the mean stress p and the third stress invariants I3.

4. On failure modelling in finite element analysis : material imperfections and element erosion
Abstract : This dissertation concerns failure modelling with material imperfections and element erosion in finite element analyses. The aim has been to improve the element erosion technique, which is simple to use and implement and also computationally inexpensive. READ MORE

5. Delamination in APS applied thermal barrier coatings : life modelling
Abstract : Thermal barrier coatings, TBCs, are used in gas turbines as a thermal shield resulting in lower temperature in coated components. The decrease of temperature allows higher gas temperatures in the turbine, which increase the efficiency. READ MORE
