van Noord, Emma (author)The increasing focus on reducing greenhouse gas emissions has led to the attractiveness of offshore hydrogen pipelines in achieving sustainable energy goals. Hydrogen, as a transport medium for energy, offers a viable alternative for transmitting large amounts of energy from offshore facilities to the shore. By storing hydrogen and subsequently...master thesis 2023

Dupain, Linda (author)According to experiments the fatigue damage behaviour of fibre reinforced polymers (FRP) experiences a load sequence effect. In this report the ability of the cohesive fatigue damage model of Dávila (2020) to simulate the behaviour after a load amplitude change is investigated. For this a double cantilever beam (DCB) with fictitious material...master thesis 2023

Ashcroft, Ian (author), Pascoe, J.A. (author)The fatigue behavior of an adhesively bonded joint is of key importance to its long-term structural integrity. However, the complex stress distribution inside a bonded joint does not make it easy to evaluate the fatigue behavior. This chapter discusses the various approaches that have been developed for predicting the fatigue behavior of...book chapter 2023

van Kuijk, J.J.A. (author)Fatigue crack growth in metals has been studied intensively for more than half a century. This research field has been closely connected to the engineering industry throughout history. It is therefore no surprise that the main focus has mostly been on developing better prediction models rather than on understanding the phenomenon of fatigue...doctoral thesis 2022

Quan, H. (author)Fatigue failures are a major concern in aeronautics. The growth of fatigue cracks in metallic structures and adhesively bonded joints has been studied for decades. Nowadays, most researchers evaluate and predict the fatigue damage growth rate (da/dN) with empirical and phenomenon based approaches, using Linear Elastic Fracture Mechanics with...doctoral thesis 2022

Āboltiņa, Laura (author)In the past years, the safety of steel railway bridges has been questioned due to the coped beam connection sensitivity to fatigue and fatigue crack appearance. To ensure the safety of these railway bridges, the propagation of the fatigue crack needs to be analysed by performing regular inspection on the bridges. The frequency of these is...master thesis 2022

Li, Z. (author), Jiang, X. (author), Hopman, J.J. (author)This paper conducts a numerical analysis on the external surface cracked steel pipes reinforced with Composite Repair System. A three-dimensional finite element (FE) model is developed to calculate the Stress Intensity Factor (SIF) of the surface crack, and the crack growth process is evaluated by the Paris’ law. The effect of FRP-to-steel...journal article 2022

Quan, H. (author), Alderliesten, R.C. (author)An energy equation for fatigue crack growth was proposed. It equates the total external work per cycle (dW/dN) to the sum of plastic dissipation (dU<sub>pl</sub>/dN), change in strain energy stored (dU<sub>e</sub>/dN) and the energy dissipated in new crack surface formation (dU<sub>a</sub>/dN). Fatigue crack growth experiment of 7075-T6 was...journal article 2022

Quan, H. (author), Alderliesten, R.C. (author)An energy equation for fatigue crack growth in adhesive joints is proposed. Fatigue experiment on DCB adhesive joint specimens was used to derive the relation between fatigue crack growth rate (da/dN) and energy variables in this equation. The result shows plastic dissipation and change in stored strain energy, whose relation with da/dN both...journal article 2022
