1. Modelling of large deformation crack propagation based on the extended finite element method
Abstract : This thesis is concerned with the finite element modelling of large deformation crack propagation, based on the extended finite element methodology. The benefit from this approach is the possibility of locally enriching the finite element space, i.e. to add a priori knowledge about the local behaviour of the solution in order to improve accuracy.

2. On the Modelling of Fracture Using Strong Discontinuities
Abstract : The major concern of this work is the constitutive and numerical modelling of fracture,based on strong discontinuity formulations. More particularly, an extended finiteelement approach is used, where the total displacement is separated in two mutuallyindependent fields, representing the continuous and discontinuous displacement respectively.

3. Long-term molecular epidemiology of extended-spectrum β-lactamase producing Escherichia coli in a low-endemic setting
Abstract : Escherichia coli is a commensal inhabitant in the gastro-intestinal tract of humans and animals but it is also the most common bacterial species causing urinary tract infection, which ranges in severity from distal cystitis to urosepsis and septic shock. During the past decades, the prevalence of antibiotic resistant E. READ MORE

5. Towards a Learning Process for Ad hoc Engineering Change Teams
Abstract : Engineering changes disrupt plans, can affect technical solutions negatively, and put project organisations under strain. However, engineering changes are a crucial part of the design process and a prerequisite in adapting to a dynamic project environment. READ MORE
