16. Computational modeling of oxygen-assisted fracture in nickel-based superalloys
Abstract : Nickel-based superalloys are a commonly used material in applications where high strength is required at high temperatures. A typical such example is jet engines and, in the case of polycrystalline nickel-based superalloys, components like turbine disks. READ MORE

17. On multiscale modeling of pearlitic steel
Abstract : By studying pearlitic steels using a scanning electron microscope it can be observed that pearlite is a two-phase material with cementite lamellae embedded in a matrix of ferrite. The cementite is commonly described as being stiff and brittle in comparison to the ferrite which is considered to have a soft and ductile mechanical behavior. READ MORE

18. Concrete Structures Subjected to Blast Loading
Abstract : The interest for building safety with regards to highly dynamic events such as close by explosion has accelerated after the recent decades of terrorist attacks. The interest has expanded from civil defence shelters and pure military targets to also include civil buildings used for different civil functions. READ MORE

19. Structure and Activity of Circular Plant Proteins : Cytotoxic Effects of Viola Cyclotides
Abstract : Cyclotides are a family of small and macrocyclic proteins that have been found in Violacaee and Rubiaceae plant species. These proteins contain a cystine knot: two disulfides bonds together with their connecting peptide backbone form an embedded ring which is penetrated by a third disulfide bond. READ MORE

20. Continuum modelling of work hardening in precipitation hardened alloys
Abstract : This thesis deals with prediction of macroscopic work hardening in a precipitation hardened alloy. The focus is on the particle contribution. A hierarchical modelling approach is adopted where work hardening in a representative material volume on the microscale is homogenized and used to represent the macroscopic hardening. READ MORE
