6. Evaluation of alternative, sustainable polymer materials in regard to mechanical properties and sustainability
University essay from Lunds universitet/Centrum för analys och syntesAbstract : We live in a world where products are consumed at an ever increasing rate, and where responsibility for the waste created is seldom taken. Plastics are in many ways wondrous materials, but they put a big strain on the environment, both in production and as waste. READ MORE

7. Energy and Strength-based Criteria for Intralaminar Crack Growth in Regions with High Stress Gradients
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Cross-ply composite laminates can develop very high density of transverse cracks in the 90-layer under severe thermal and mechanical loading conditions. At such high crack densities, two adjacent cracks start to interact, and a stress gradient is created in the region between these cracks. READ MORE

8. Monitoring and Modelling of the Abiskojåkka Bridge
University essay from Luleå tekniska universitet/Byggkonstruktion och brandAbstract : The infrastructure of today is getting older and problems caused by deterioration over time is affecting the service life of these structures. In Sweden most of the existing bridges were constructed 60 to 70 years ago, rising the need to determine the state of health of the bridges as the maintenance costs will increase heavily. READ MORE

9. Thermomechanical stress analysis of the main insulation system of traction electrical machines
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : More efficiency heavy-duty vehicles are developed with higher range, updated electronic and mechanical parts. The fuel efficiency and pollution of carbon dioxide need to be lower to achieve new EU regulations. The global population increases with an increased number of heavy-duty vehicles. This, in turn, increases the emission. READ MORE

10. Modelling of Laser Welding of Aluminium using COMSOL Multiphysics
University essay from KTH/MaterialvetenskapAbstract : This thesis presents a modelling approach of laser welding process of aluminium alloy from the thermo-mechanical point of view to evaluate the occurrence of hot cracking based on simulation results and relevant criteria. The model was created stepwise in COMSOL Multiphysics, starting with the thermal model where heat conduction of solid and liquid phase was computed. READ MORE
