Stambaugh, K.A. (author)Ships must perform their missions with a high degree of reliability to maximize availability through their service life. The ultimate safety of the hull structure is time-dependent with degradation caused by the operational environment. Achieving the fore mentioned reliability and mission availability requirements are complicated because ships...doctoral thesis 2020

Rodenburg, Jorrit (author)Offshore wind turbines are designed to persist harsh environmental conditions, including corrosion. Pitting corrosion is one of the most dangerous forms of corrosion. In combination with a fatigue loading, a corrosion pit could result into the failure of a structure, due to a minimal weight reduction. Of the corrosion fatigue process, the...master thesis 2020

Malschaert, David (author)In the course of this thesis, a research has been conducted to the application of fracture mechanics on an othotropic steel deck (OSD). Obtaining accurate predictions of crack path and fatigue life assessment were the main objectives for this thesis. As 3D crack propagation modelling in orthotropic steel decks is an arduous task, simpler studies...master thesis 2020

Raimondo, A. (author), Doesburg, S.A. (author), Bisagni, C. (author)In this work, an approach based on the Virtual Crack Closure Technique, included in the commercial finite element code ABAQUS, is adopted to study the propagation of delamination in composite structures under quasi-static and fatigue loads. The methodology, originally capable of simulating only delamination under quasi-static loads, has...journal article 2020

Sahu, Saswat (author)Functionally graded materials (FGMs) represent a new class of materials that consist of graded compositional and microstructural patterns allowing to tailor properties. Additive manufacturing (AM) or more commonly known as 3D-printing offers a paradigm shift in FGMs and engineering design due to its ability to produce components with complex...master thesis 2020

Pedrosa, Bruno (author), Correia, José A.F.O. (author), Rebelo, Carlos A.S. (author), Veljkovic, M. (author)In North America and Europe, there is a significant number of centenary metallic bridges that require maintenance and strengthening operations. These structures need to be adapted to increasing traffic intensities, and their structural integrity should be constantly evaluated. Fatigue damages were not considered in the original design of old...journal article 2020

Wang, H. (author), Liu, X. (author), van de Ven, Martin (author), Lu, Guoyang (author), Erkens, S. (author), Scarpas, Athanasios (author)Recently warm mix asphalt (WMA) technologies have been introduced to rubberized asphalt mixtures to decrease the required construction temperatures and to alleviate the hazardous gas emissions. Rubberized asphalt pavements combining with WMA have the potential to improve the long-term pavement performance. This study aims to investigate the...journal article 2020

Ferreira Motta Junior, R. (author), Alderliesten, R.C. (author), Shiinoc, Marcos Yutaka (author), Cioffia, Maria Odila Hilário (author), Voorwald, Herman Jacobus Cornelis (author)Current models for delamination propagation prediction in fiber-reinforced polymer (FRP) composites exhibit limitations to explain the physics underlying the mechanisms of damage formation in fatigue. In order to contribute in this field, this research focuses on the study of damage development within a single loading cycle of FRP double...journal article 2020

Vaalburg, Léon (author)The fatigue strength of the pin connection is assessed in the research project presented in this thesis. The fatigue strength is quantied by an estimated fatigue lifetime, which is the expected time to failure of the most critical point in the connection. The lifetime is estimated based on the yearly accumulated fatigue damage. A computer model...master thesis 2019

Rajpal, D. (author), Kassapoglou, C. (author), De Breuker, R. (author)An analytical model to predict the fatigue life of a composite laminate is formulated. The model calculates stresses in each ply using classical lamination theory, degrades the residual strength using the linear wear-out law and predicts failure based on Tsai Wu failure theory. The cycles to failure are predicted using the updated cycle-by...journal article 2019

Blok, Adriaan (author)Selective laser melting (SLM) is an additive manufacturing technique, which is currently on the rise of being used for manufacturing bone implants. Spinal cage, dental and hip implants can for example be manufactured using SLM. Ti6Al4V lattice structures, categorised as metamaterials, can be printed by SLM with mechanical properties close to...master thesis 2019

Lee, Jaehyeun (author)Fatigue is often a governing design factor for offshore wind turbines. Since the design of offshore wind turbines includes conservatism, the actual accumulated fatigue damage can be lower than what the turbine is designed for. In this case, the operator can make a decision on life time extension of existing wind turbines. Therefore, it is...master thesis 2019

van Maris, Rutger (author)This thesis presents a model that is able to predict fatigue crack growth and damage directionality in non-conventional Fibre Metal Laminates (FMLs) in CentreCracked Tension (CCT) specimens. Non-conventional FMLs encompass all FMLs other than standardised ones such as GLARE. FMLs can be made non-conventional by using multiple fibre types, any...master thesis 2019

ter Meulen, Ruben (author)A random periodic two-dimensional spring network us built using a Poisson disk distribution and computing the Delaunay triangulation of the centers of the disks. The edges of the network represent springs that obey Hooke’s law with an adjustment on the spring constant. The adjustment allows spring to soften and to break. The two-dimensional...bachelor thesis 2019

Gunecha, Saurabh (author)Orthotropic bridges are being built for more than half a century. These bridges are prone to high cycle fatigue due to traffic loading. Early onset of fatigue cracking is a serious issue in both old and recently built bridges. To prevent this a number of different cross section have been suggested. Sandwich Panel is one of the suggested...master thesis 2019

Rikeros Orozco, Daniel (author)There are several methods to perform fatigue assessment as described by the Eurocode 3 and the International Institute of Welding (IIW). The codes establish the relation between stress ranges and their respective number of cycles until failure of the detail. This method is called S-N curves, however this is based mainly on nominal stresses. A...master thesis 2019

Hillen, Huub (author)In the last century, the offshore industry has installed a network of offshore pipelines in the southern North Sea. Due to decreasing oil and gas extraction in the North Sea, many pipelines of this network are becoming redundant. A potential option for the reuse of these pipelines is the transport and storage of gaseous hydrogen, which is...master thesis 2019
