2. Fatigue strength of welds in 800 MPa yield strength steels : Effects of weld toe geometry and residual stress
Abstract : Nowadays there is a strong demand for lighter vehicles in order to increase the pay load. Through this the specific fuel consumption is decreased, the amount of greenhouse gases is lowered and the transport economy improved. One possibility to optimize the weight is to make the components from high strength steels and join them by welding. READ MORE

3. On inelastic local flange buckling
Abstract : This thesis deals with inelastic local buckling of I-beam flanges made of steel. The main focus is on the theoretical description of the buckling process, and the influence of various parameters, e.g. the plastic modulus, yield plateau, yield stress etc. READ MORE

5. Addressing water scarcity in the Bolivian Altiplano for sustainable water management
Abstract : Water scarcity is a consequence of complex interactions between water access and water use. In fact, the time period over which precipitation deficit accumulates is a determing factor for the occurrence of drought. Drought induces crop production losses and far-reaching societal effects. In the South American Altiplano, drought is a major hazard. READ MORE
