26. Predicting Sheared Edge Characteristics of High Strength Steels
Sammanfattning : An efficient way of reducing CO2 emissions from the transportation sector is to reduce the vehicle weights, i.e. lightweighting. A common strategy for lightweighting of vehicles is to replace the steels used to build structural parts of the vehicle, usually manufactured by metallic sheets, with stronger, advanced high strength steel (AHSS) grades.

27. Modelling of fracture toughness using peridynamics : A Study of J-integral, essential work and homogenisation
Sammanfattning : 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. LÄS MER
28. Mechanical Characterization of Heterogeneous Brittle Materials
Sammanfattning : Comminution is one of the highest energy-consuming processes in the mining and mineral processing industry by consuming around 2% of the global generated energy with an overall efficiency of 1-3%. Different approaches to the optimization of processes have been developed, but there is still room for improvement. LÄS MER
29. Full-Scale Modelling and Simulation of Bucket Filling and Wear for Mining Rope Shovels
Sammanfattning : Handling of granular material occurs all over the world for different reasons and under different conditions. In the mining industry, granular material handling is present in almost all processes. The machinery that deals with the granular material is typically subjected to significant wear. The loading process is a very crucial task in any mine. LÄS MER
30. Heterogeneous Bonded Particle Modelling of Rock Fracture
Sammanfattning : The dynamic fracture process of rock materials is of importance for several industries, such as the rock drilling process in geothermal and mining applications. Gaining knowledge and understanding of dynamic rock fracture through numerical simulations can enhance the rock drilling process, for example by optimising the drill bit geometry and drilling parameters.
