1. Fracture simulation with a hyperelastic phase field model
University essay from KTH/HållfasthetsläraAbstract : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.

2. Analysis of hot workability in 316L steel using ductile fracture criterions
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : The focus of this thesis is to develop a simulation model for predicting ductile fractures during hot working at Alleima. The main fracture mechanism in these conditions is ductile fracture by void coalescence. The ductile fractures are caused by the linking of voids that appear when there is large plastic deformation near second-phase particles. READ MORE

3. Performance Evaluation of a High Temperature Borehole Thermal Energy Storage Under Influence of Groundwater Flow
University essay from KTH/EnergiteknikAbstract : Recent years have seen a growing interest in large-scale high-temperature borehole thermal energy storage (HT-BTES) as a means to store industrial waste heat and solar energy between the seasons. A profound understanding and characterization of the thermal and hydraulic processes involved in such systems is required for the optimal design as well as for environmental assessments of the storage.

4. Dynamic Finite Element Modelling of a Fall on the Hip
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : Assessing the risk of future femur fracture is an important step in preventing this serious and common injury. The current methods to predict the fracture risk are typically based on bone mineral density measurement, used as a surrogate for femoral strength. READ MORE

5. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints
University essay from KTH/LättkonstruktionerAbstract : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration. Nowadays, the state-of-art joining technique for primary aircraft composite structures, such as fuselage barrels, is still mechanical fastening. READ MORE
