11. Cases of coupled vibrations and prametric instability in rotating machines
Abstract : The principal task in this research project was to analyse the causes and consequences of coupled vibrations and parametric instability in hydropower rotors; where both horizontal and vertical machines are involved. Vibration is a well-known undesirable behavior of dynamical systems characterised by persistent periodic, quasi-periodic or chaotic motions. READ MORE

12. Modelling of fracture toughness using peridynamics : A Study of J-integral, essential work and homogenisation
Abstract : Fracture toughness is one of the most important properties of a material. Being able toaccurately estimate the energy that goes into forming new crack surfaces is essential for the development of new materials, quality assurance, structural monitoring and failure analysis. READ MORE

13. Numerical prediction of wear in industrial raw material flow
Abstract : Abrasive wear is largely involved in many industrial processes, and has far reaching economic consequences which involve not only the costs of replacement, but also the costs involved in machine downtime and lost production. Constructions and machines like conveyers, chutes and dumper truck bodies are often exposed to abrasive wear during handling of industrial raw granular material flow e. READ MORE

14. On mechanical characterization and multi-scale modeling of Lithium-ion batteries
Abstract : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. READ MORE

15. On structural integrity with emphasis on rate effects of fracture toughness
Abstract : This thesis is concerned with structural integrity from a fracture mechanics point of view. The emphasis in this work is on rate effects of fracture toughness but all investigations deal with phenomena or problems within the frame work of non-linear fracture mechanics. READ MORE
