Wanhill, R.J.H. (author)The requirements and problems of high temperature materials in gas turbines are reviewed, with specific reference to turbine discs, blades, vanes and combustion cans. The mechanical and environmental property requirements of these components are discussed, followed by an overview of the types of materials used. Lastly, there is a summary of the...report 1975

Panjeh Shahi, E. (author)Hollow sections are most suitable for welded connections between members. The welding procedure is fairly straightforward in RHS, because they do not require profiling which is necessary for circular hollow sections. Although many multiplanar and uniplanar joints in structures are present, limited evidence is available for the fatigue behaviour...journal article 1995

Liu, G. (author)Montmorillonite (Mt) nanoclay is a layered silicate mineral with a 2:1-type layer structure, two tetrahedrals sandwiching one octahedral. In recent decades, it is successfully introduced into polymer systems to form polymer-clay nanocomposites (PCN) in which the silicate layers of the Mt are randomly and homogeneously dispersed at a molecular...doctoral thesis 2011

Qian, C. (author)In this research, extensive fatigue tests were performed on single glass fibres and composite coupons. Comparison of the test results shows that there is a significant difference between the fibre and composite fatigue behaviour. In order to clarify this difference, a multi-scale micro-mechanical model was developed. This model predicts fatigue...doctoral thesis 2013

Anijs, M.A. (author)Low cycle corrosion fatigue is an interesting issue in civil Engineering because it may effect the lifetime of structures in negative and unexpected ways. However, analysis of design codes has revealed that low cycle corrosion fatigue is not a major issue in the design of offshore structures because these structures are designed with a global...master thesis 2013

Lahuerta, F. (author), Westphal, T. (author), Nijssen, RPL (author), van der Meer, F.P. (author), Sluys, Lambertus J. (author)The aim of this work is to study the thickness effect in static and fatigue tests of glass-fibre unidirectional compression coupons. For this purpose, the self-heating effect, the effect of specimen geometry, and the influence of the manufacturing processes have been minimized. A scaled thickness compression coupon has been designed with the...conference paper 2014

Chrysafopoulos, D. (author)Fatigue loads and failures in metallic structures are a well-known technical problem. Commonly, the fatigue life of the steel elements is determined by an analytical calculation using S-N curves as design resistance to periodic action. However, the technological improvements in almost all structures continuously stretch the limits of acceptance...master thesis 2014

Van Eeden, F.M. (author)Marine and offshore structures are continuously exposed to different loading types. Cyclic loads results in cyclic stresses in structural components, which may result in degradation of the structural integrity. This process is called fatigue. Fatigue damage of structural components usually occurs without any —global— visible sign. Ultimately,...master thesis 2015

Rabe, P. (author)Offshore oil & gas production is an industry where breaking records has become a necessity. So-called unconventional oil in ultra-deep water (2000 m+) requires rethinking of current production techniques, as steel tubing begins to buckle under its own weight. Other problems arise from corrosion of pipelines at all depths, requiring expensive...master thesis 2015

Latifi, M. (author), van der Meer, F.P. (author), Sluys, Lambertus J. (author)This paper presents a new discontinuous damage model for simulating fatigue-driven delamination in composites. Fatigue models commonly describe crack growth using the Paris law which provides the link between the energy released due to delamination and the crack growth rate. A core issue in implementing the Paris law is to accurately compute the...conference paper 2016

Alderliesten, R.C. (author)The appropriateness of some common similitude principles with respect to describing and predicting fatigue damage propagation is discussed. Linear elastic fracture mechanics have provided a basis to describe damage growth using stress intensity factors or strain energy release rates, both related to the work of Griffith and Irwin. The fatigue...journal article 2016

(author)The present study utilizes a state-of-the-art stochastic modeling with structural health monitoring (SHM) data derived from strain measurements, in order to assess the remaining useful life (RUL) online in composite materials under fatigue loading. Non-Homogenous Hidden Semi Markov model (NHHSMM) is a suitable candidate with a rich mathematical...journal article 2016

Hogeveen, J.J. (author)Conventional theories to describe and predict FCG are based on a SIF parameter, ΔK. If ΔK is used as similitude parameter to predict FCG, an R-effect arises. This R-effect can be accounted for by means of plasticity induced crack closure: A plastic wake behind the crack tip causes the crack to close before a zero tensile load is applied. As such...master thesis 2016

Kouka, A. (author)Project Code: OE54015, OE54030. The potential of offshore wind is enormous. The wind resource offshore is generally much greater than onshore, especially at bigger water depths. Expanding prudently into the sea leads to bigger support structures for the wind turbine. Therefore, the need for optimized designs, which will establish the wind energy...master thesis 2016

Amiri Rad, A. (author), Mashayekhi, Mohammad (author), van der Meer, F.P. (author)This paper deals with high cycle fatigue delamination in composite materials. The cohesive zone approach along with the level set method is used to simulate fatigue-driven delamination growth. The cohesive zone method is used for calculation of the energy release rate at the crack front because of its superiority over the virtual crack...journal article 2017

Hengeveld, S. (author)Recently a new framework to predict fatigue crack growth has been developed based on the Thick Level Set method. The aim of this thesis is to extend this framework to allow for realistic loading spectra. First, a calibration method for this framework is presented. This method decouples crack growth, defined by a Paris like equation, from the...master thesis 2017
