1. Modelling of fracture toughness using peridynamics : A Study of J-integral, essential work and homogenisation
Sammanfattning : 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. LÄS MER
2. 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
3. On the fracture behaviour of softwood : a combined experimental and computational study of the interaction between fracture behaviour and material anatomy
Sammanfattning : 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. LÄS MER
4. Tensile fracture of ice : test methods and fracture mechanics analysis
Sammanfattning : This thesis is concerned with several aspects of fracture of both brackish (low salinity) sea ice and freshwater ice. The tests and analyses are confined to tensile, or in fracture mechanics language, Mode I, fracture. LÄS MER
5. Linear and Nonlinear Mechanics of Lattice Materials : Computational Modelling and Experiments
Sammanfattning : Lattice materials are artificial materials made of repeating unit-cells. The internal architecture of these materials can be engineered for a specific application such as energy absorption, heat transfer, or acoustic damping. LÄS MER
