1. Impact of Residual Stress on the Warm Pre-Stressing Effect
University essay from KTH/HållfasthetsläraAbstract : Irradiation of a reactor pressure vessel (RPV) causes a shift of the ductile to brittle transition region towards higher temperature regions. In the event of a pressurized thermal shock (PTS), where the temperature drops drastically, the ductile to brittle transition region might be entered for irradiated ferritic steel. READ MORE

2. Examination of a Damaged Slitting Knife using Scanning Electron Microscopy and Finite Element Simulations
University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Abstract : At voestalpine Precision Strip AB, the slitting process is used frequently. Slitting is a commonly applied manufacturing technique during sheet metal processing that aims to split large coils of sheet metal into narrower widths. READ MORE

3. Interaction between weld residualstresses and warm pre-stressing
University essay from KTH/HållfasthetsläraAbstract : Cleavage fracture is a catastrophic phenomenon as it is a sudden structural collapse occurring to structures made of insufficiently ductile steels working at lower temperatures. In this study, the focus is on the material used in reactor pressure vessels (RPV) in nuclear power plants. READ MORE

4. Cleavage fracture toughness at varying specimen size and crack depth
University essay from KTH/Hållfasthetslära (Avd.)Abstract : Cleavage fracture is one of the most severe failure modes in low alloy ferritic steel structures and the fracture toughness is strongly dependent on the size of the specimen, crack depth and temperature. This thesis investigates how the fracture toughness is affected under conditions that relates to size and constraint effects through a fracture mechanical experiment test series. READ MORE
