1. Modelling of fracture toughness using peridynamics : A Study of J-integral, essential work and homogenisation
Abstract : 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. READ MORE

3. Numerical methods and multi-scale modeling for phase-field fracture - With applications in linear elastic and poro-elastic media
Abstract : This thesis presents novel numerical methods and a multi-scale modelling framework tailored for advancing the phase-field fracture model with applications in linear elastic and poro-elastic media. In the realm of the numerical methods, the focus lies on devising computationally efficient and robust monolithic solution techniques. READ MORE

4. On the fracture behaviour of softwood : a combined experimental and computational study of the interaction between fracture behaviour and material anatomy
Abstract : The propensity for fracture, i.e. failure through separation of the material, is a factor that must be regarded in the design of wooden structures, but also in wood machining operations and drying. READ MORE

5. Non-Linear Vibration and Dynamic Fracture Mechanics of Bridge Cables
Abstract : In the present work, the non-linear vibrations and the corresponding dynamic fracture mechanics of cables of cable-stayed bridges are studied. The cables are among the most critical components in cable-stayed bridges and there are different damage sources such as corrosion, vibration, fatigue and fretting fatigue that can significantly affect them, thereby reducing the cable’s service life and even producing their failure.
