1. Modeling and experimental characterization of large biaxial strains and induced anisotropy in pearlitic rail steel
Abstract : Large shear strains accumulate in the near-surface region under the running band of railway rails. In this region, rolling contact fatigue cracks often initiate, causing major problems for the railway industry. READ MORE

2. Modeling and experimental characterization of pearlitic rail steels subjected to large biaxial strains
Abstract : Large shear strains develop in the near-surface region under the running band of railway rails. Rolling Contact Fatigue (RCF) cracks often initiate in this region, causing major problems for the railway industry. However, characterization of the constitutive and fatigue behavior of this region is difficult due to the large gradient of properties. READ MORE

3. Modelling of the cyclic behaviour of superalloys
Abstract : In the aviation industry today there is a trend of increasing operating temperatures in turbine engines. The advantages with higher temperatures in the engines are improved performance and efficiency. READ MORE

4. Modeling of Inelastic Response of Metals with Emphasis on Cyclic Viscoplasticity
Abstract : This thesis is concerned with the continuum modeling of the macroscopic behavior of engineering metals, in particular as part of life prediction strategies. Focus is primarily placed on the formulation and numerics of models for cyclic rate-dependent response. READ MORE

5. On the modeling of large ratcheting strains and anisotropy in pearlitic steel
Abstract : Thermodynamically consistent constitutive material models for describing the large strain response of polycrystalline metals are proposed. Emphasis is put on the multiaxial ratcheting under cyclic loading and the evolution of anisotropy in pearlitic steel. READ MORE
