16. Modelling and simulation of plastic deformation on small scales : interface conditions and size effects of thin films
Abstract : Contrary to elastic deformation, plastic deformation of crystalline materials, such as metals, is size-dependent. Most commonly, this phenomenon is present but unnoticed, such as the effect of microstructural length scales. READ MORE

17. On the Role of Interfaces in Small Scale Plasticity
Abstract : The strong evidence for a size dependence of plastic deformation in polycrystalline metalsis the basis for the research presented in this thesis. The most important parameter for this, and arguably also the most well known, is the grain size. As the size of the grains in a microstructure is decreased the yield stress increases. READ MORE

18. Modelling the Evolution of Species’ Ranges
Abstract : The fact that species have limited ranges is often due to a limited ability to adapt to the environmental conditions that occur outside their geographic ranges. However, due to ongoing climate change, the environmental conditions within species’ geographic ranges may change in the near-future. READ MORE

19. 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

20. 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
