1. Computational homogenisation and solution strategies for phase-field fracture
Sammanfattning : The computational modelling of fracture not only provides a deep insight into the underlying mechanisms that trigger a fracture but also offers information on the post-fracture behaviour (e.g., residual strength) of engineering materials and structures. LÄS MER
2. Phase field modeling of flaw-induced hydride precipitation kinetics in metals
Sammanfattning : Hydrogen embrittlement can manifest itself as hydride formation in structures when in contact with hydrogen-rich environments, e.g. in space and nuclear power applications. To supplant experimentation, modeling of such phenomena is beneficial to make life prediction reduce cost and increase the understanding. LÄS MER
3. Numerical methods and multi-scale modeling for phase-field fracture - With applications in linear elastic and poro-elastic media
Sammanfattning : 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. LÄS MER
4. Macroscale Modelling of 3D-Woven Composites: Inelasticity, Progressive Damage and Final Failure
Sammanfattning : Composites with 3D-woven reinforcement have been slowly making their way into different industrial applications. The interlacement of yarns, not only in-plane but also through-thickness, means that in many applications 3D-woven composites can outperform their laminated counterparts. LÄS MER
5. Tin whiskers: experiments and modelling
Sammanfattning : Tin whiskers are hair-like single crystals that spontaneously grow from tin-coated surfaces. Whiskers are commonly found in electronic components, where tin coatings are used in, e.g., soldering applications, and to protect components from corrosion. LÄS MER
