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. 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
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
Sammanfattning : This thesis consists of two scientific papers on strength and fracture of embossed tissue paper. In Paper A an experimental study of embossed tissue paper is presented. The mechanical properties of most soft tissue paper are to a large extent governed by the creping and subsequent embossing process. LÄS MER
Sammanfattning : Railway structures represent complex mechanical problems involving wave propagation, plastic deformations and material degradation. The wheel-rail contact loads subject the material to repeated cycles of complex stress states resulting in rolling contact fatigue (RCF). LÄS MER
