Surface Crack Growth in Metallic Pipes Reinforced with Composite Repair System

Surface cracks are serious threats to the structural integrity of offshore metallic pipes. This dissertation proposes a protocol of composite reinforcement on surface cracked metallic pipes subjected to cyclic loads, aiming to decrease the crack growth rate and prolong the residual fatigue life. The main objective of this dissertation is to...

High Order Adaptively Integrated Cohesive Elements: Development, implementation and testing on composite delamination

Composite delamination represents one of the most critical failure mechanisms occurring in composite structures. In case complex structures are being designed, numerical methods need to be employed. One of the methods to numerically simulate delamination in a Finite Element environment is through the employment of the Cohesive Elements, which...

Application of fracture mechanics in a blended numerical framework for progressive damage analysis of CFRPs in FEM

Composite structures are increasingly applied for their unique set of properties. However, their behavior is not yet fully understood, amongst others, due to complex interactions of failure modes. This research implemented a blended stress-strain and fracture mechanics based progressive damage analysis model, based on a Continuum Damage Model ...

Progressive damage modelling of FRPs using a blended stress-strain and fracture mechanics approach in FEM

Despite great strides made in understanding and modelling Fiber-Reinforced Polymers (FRPs), their full potential is held back by the inability to accurately predict failure. Contrary to past attempts focused on isolated application of stress-strain and fracture mechanics based failure theories, this research builds upon the existing framework by...
