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. Mixed mode loaded adhesive layers : from measurement of material data to analysis of structural behaviour
Sammanfattning : In manufacturing of multi-material products, a joining method that is able to cost-effectively assemble components made of dissimilar and similar material, with irregular geometries, is optimal. As an alternative, adhesive bonding is in-creasingly adapted by the industry, which is also used in manufacturing of multi-phase materials. LÄS MER
3. Mechanical Recycling of Engineering Thermoplastics using Alloying Techniques
Sammanfattning : The aim of this thesis is to indicate routes by which recycled engineering thermoplastics (ETP) can be upgraded using alloying techniques. Recycled ETP have often been subjected to long-term service-induced degradation, so that the residual properties of recycled ETP need to be improved. LÄS MER
4. Shear Behaviour of Adhesive Layers
Sammanfattning : An experimental method to determine the complete stress versus deformation relation for a thin adhesive layer loaded in shear is presented. The work is based on a classical specimen geometry, i.e. the end-notch flexure specimen (ENF-specimen) and the experiments are evaluated based on an inverse method. LÄS MER
5. Application of cohesive modeling in joining technology
Sammanfattning : ABSTRACTThis thesis summarizes the development of cohesive modeling of joints. It presents some new developments regarding the effects of non-zero thickness of adhesive layers and a novel approach of using the concept of cohesive modeling to characterize the failure behavior of rivet joints.
