Blom, A.W. (author)The use of fiber-reinforced composites in aerospace structures has increased dramatically over the past decades. The high specific strength and stiffness, the tailorability, and the possibilities to integrate parts and reduce the number of fasteners give composites an advantage over metals. Automation of the production process enables large...doctoral thesis 2010

Şen, I. (author)The lower wing skin is one of the primary structures of an aircraft. To further improve the fatigue and damage tolerance (F&DT) performance of the lower wing, fibre metal laminates (FML) are proposed as a new material solution. FML consist of thin metal layers bonded with layers of fibre composites. This concept has potentially a large design...doctoral thesis 2015

Knijnenberg, A. (author)Since the development of the first truly synthetic fibres in the late nineteenth century, scientific efforts have lead to large variety of fibres ranging from fibres for textile applications to high performance fibres used as engineering materials. Examples of high performance fibres that are often used in engineering applications are aramid,...doctoral thesis 2009

Teuwen, J.J.E. (author)In previous research, the potential of glass fibre reinforced anionic polyamide-6 (APA-6) composites for use in wind turbine blades was proven. Based on polymer properties, viscosity, processing time, costs and recyclability, APA-6 composites are considered the most suitable reactive thermoplastic material candidate. However, more research is...doctoral thesis 2011

Vervenne, K. (author)The research presented in this thesis deals with gradient-enhanced approximate design optimization. This research has been carried out as part of the ADOPT project (Approximate Design OPTimization), a joint STW project with the Eindhoven University of Technology. In structural optimization, sensitivity analysis is often performed by means of the...doctoral thesis 2005

Khani, A. (author)Automated fibre placement (AFP) machines are able to place simultaneously several bundles of fibres, called tows, on a surface. Using AFP machines, it is also possible to manufacture composite laminates with fibres placed in curvilinear paths. The fibre orientations and stiffness properties of these laminates are spatially varied and hence they...doctoral thesis 2013

Vries, J. De (author)Imperfections are irregularities of the shape of a thin-walled shell, such as those used for rocket structures or silos. Knowing the imperfections is very important as thin-walled shells are very sensitive to imperfections. Even a small deviation with respect to the perfect shell shape reduces the buckling load significantly. The main objective...doctoral thesis 2009

Carpentieri, G. (author)This thesis presents a shape optimization framework for problems that are encountered routinely in Aerodynamic Design. The nature of the framework is numerical. Its focus is wide as different aspects of the shape optimization practice are treated, e.g., the solution of the flow equations, the sensitivity analysis and the parameterization of the...doctoral thesis 2009

Yao, L. (author)Advanced composite materials have been commonly used in aerospace engineering, because of their good mechanical properties and attractive potential for creating lightweight structures. Susceptibility to delamination is one of the most important issues in the applications of these materials. This disadvantage can prohibit the application of...doctoral thesis 2015

Van den IJssel, J.A.A. (author)Atmospheric density models are currently the limiting factor in the accuracy of the dynamic orbit determination and prediction of satellites in a low Earth orbit. Any improvement in these models would greatly aid in applications such as re-entry prediction, ground-track maintenance of Earth observation satellites and forecast of possible...doctoral thesis 2014

Van den Ende, D.A. (author)The piezoelectric effect, which causes a material to generate a voltage when it deforms, is very suitable for making integrated sensors, and (micro-) generators. However, conventional piezoelectric materials are either brittle ceramics or certain polymers with a low thermal stability, which limits their practical application to certain specific...doctoral thesis 2012
