1. 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

2. A Damage-Based Interface Model: Application to the Degradation and Failure of a Polycrystalline Microstructure
Abstract : A constitutive model for material interfaces is presented. The model is based on damage coupled to plastic (or viscoplastic) slip and dilatation, and it is able to describe the successive degradation and failure of an interface. READ MORE

3. Anisotropy in pearlitic steel subjected to rolling contact fatigue - modelling and experiments
Abstract : In rails and wheels subjected to severe rolling/sliding contact, large plastic deformations accumulate in the surface layer. This decreases the fatigue resistance of components and makes this layer prone to formation of common rolling contact related defects. READ MORE

4. Physically based models of metal plasticity
Abstract : This work is focussing on the material modelling aspects in simulation of forming processes. The research question is: Do physical based material models have any advantages compared to the more common type of engineering models used in simulation of forming processes? The success of performing useful simulations of forming processes depends very much on the accuracy of the used material description. READ MORE

5. Modeling and Simulation of CGI Machining on Microstructure Level
Abstract : incorporation of new design materials – e.g. in order to promote lightweight design – oftenleading to significant changes in manufacturing conditions, which can be assessed in anefficient way by simulation rather than more expensive testing. READ MORE
