1. On Cohesive Modelling of Carbon/Epoxy Composites : Delamination and Fibre Compressive Failure
Sammanfattning : Carbon Fibre Reinforced Polymers are widely used in engineering applications where weight saving and high mechanical performance are a key factors. However, an inheren tweakness of laminated CFRP:s is there relatively low resistance to delamination. Therst part of this thesis is devoted to extract cohesive laws associated with delamination.

2. 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.

4. Modelling of Delamination Growth in Composite Structures
Sammanfattning : Delaminations constitute an important damage and failure mode in polymeric composite laminates. In order to explicitly incorporate and model the delamination progression within a finite element analysis, the meso-modelling concept is applied in the present work. The laminate is thereby represented by separate layers connected with interfaces. LÄS MER
5. Modelling the time-dependent, damage and fracture mechanical properties of load-bearing soft biological tissues
Sammanfattning : Load-carrying soft biological tissues exhibit a wide range of complex time-dependent, damage, and fracture mechanical properties. An effective comprehension of such behaviour is advantageous in characterising tolerance to injury and can provide valuable insights regarding the incidence and progression of certain diseases.
