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. Failure Modeling of Curved Composite Beams : Numerical Modeling of Failure Onset and Propagation in L-Profile Beams
University essay from KTH/LättkonstruktionerAbstract : The high strength/stiffness-to-weight ratio that composite materials exhibit has led to the utilization of composites as alternative to traditional materials in weight-critical applications. However, the highly anisotropic nature of composites renders the strength prediction under complex loading challenging. READ MORE

3. Simulation of Delamination Migration in Laminated Composite Structures - An Approach Combining Extended Finite Elements and a Cohesive Zone Model
University essay from Lunds universitet/HållfasthetsläraAbstract : Fiber-reinforced polymer matrix composites are being used increasingly in lightweight applications where high strength and stiffness is required. One of the main challenges with designing components from such materials is to predict the ultimate strength and behaviour of the structure. READ MORE

4. Prediction of fracture propagation in human femur using the Finite Element Method
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : Hip fractures constitute a major problem, both in terms of a lower life quality for the people affected and socio-economical factors. Osteoporosis is a medical condition, defined by decreased bone mass, which results in a more fragile bone structure and a higher risk for fractures. Osteoporosis accounts for a cost of € 1. READ MORE

5. Linear and non-linear FE-analysis of cracking behavior of wing walls in integral bridges
University essay from Lunds universitet/Avdelningen för KonstruktionsteknikAbstract : Wing walls on slab frame integral bridges has traditionally been designed for mainly earth pressure and its self-weight. It has also been designed separately from the rest of the bridge. Traditionally no 3D effects have been considered in the design of the wing walls. READ MORE
