21. Tooth Interior Fatigue Fracture&Robustness of Gears
Abstract : The demands the automotive gear designer has to considerduring the gear design process have changed. To design a gearthat will not fail is still a challenging task, but now lownoise is also a main objective. Both customers and legalregulations demand noise reduction of gears. Moreover, thequality of the product is more in focus than ever before. READ MORE

22. System-in-a-Package on Low-Cost Liquid Crystal Polymer Substrate
Abstract : System-in-a-Package (SiP) is one of the most advanced approaches to meet the requirements for future high-density electronics packaging. In this thesis, a 3D system-in-a-package concept with embedded active and passive components is proposed, where a liquid crystal polymer (LCP) was used as the base substrate. READ MORE

23. Prevention of Head Injuries - focusing Specifically on Oblique Impacts
Abstract : The massive number of injuries sustained in trafficaccidents is a growing problem worldwide, especially indeveloping countries. In 1998, more than one million peoplewere killed in traffic accidents worldwide, while about tentimes as many people were injured. READ MORE

24. Modeling of phase transformations and cyclic plasticity in pearlitic steels
Abstract : The low rolling resistance in railway transportation is a key factor for its high efficiency, but it comes at the price of very high contact pressure between the rail and wheel. Due to the high stresses and the large number of load cycles during railway operation, both the rail and the wheel can be susceptible to fatigue crack initiation and propagation. READ MORE

25. Mechanics and Failure in Thin Material Layers : Towards Realistic Package Opening Simulations
Abstract : The final goal of this PhD-work is an efficient and user-friendly finite element modelling strategy targeting an industrial available package opening application. In order to reach this goal, different experimental mechanical and fracture mechanical tests were continuously refined to characterize the studied materials. READ MORE
