van Dooren, K.S. (author)
The aeronautical industry has set ambitious goals to reduce its environmental impact and become sustainable. Addressing rising emissions involves strategies such as reducing structural weight, due to its direct impact on fuel consumption, and the use of new materials and manufacturing techniques. Research and development on thermoplastic...

Kootte, Lucas (author)
A building block pyramid is designed used to evaluate a composite aircraft structure, combining tests and analyses, using stiffened panels, single-stringer specimens and coupons. Failure in these structures can be caused by postbuckling-induced skin-stringer separation, which is complex, involving matrix cracks, fibre bridges, and delamination...

Tijs, B.H.A.H. (author)
Thermoplastic composites enable new manufacturing techniques such as conduction welding to make the aviation industry more sustainable, while at the same time, provide great benefits to cost-efficient high-volume production. One of the benefits of welding is that it reduces the amount of mechanical fasteners required. Fastener-free joining also...

Gutierrez Alvarez, J. (author)
A big technological leap in Carbon Fibre Reinforced Plastics (CFRP's) has brought to the market materials that are able to operate under severe thermomechanical loading conditions and yet remain lightweight. This is of high interest for new developments in aerostructures, such as supersonic airliners or the hydrogen aircraft. A continuous need...

Binder, S. (author)
Future composite aircraft wing designs will exploit anisotropic material properties by aeroelastic tailoring and include active control methods for manoeuvre and gust load alleviation. The research focuses on the simultaneous optimisation of aeroelastically tailored wing structures with active manoeuvre and gust load alleviation as well as the...

Rajpal, D. (author)
The COVID-19 pandemic had a significant impact on the aviation industry with more than 60% reduction in the passenger traffic in the year 2020 compared to year 2019. The passenger traffic which is now expected to reach the 2019 level only around the year 2024 will still continue to grow but at a lower pace compared to the pre pandemic levels....

Natella, M. (author)
The process of designing an aircraft is generally divided in three phases, namely the conceptual, preliminary and detailed. The whole process is one that involves various disciplines and is subject to multiple constraints. Traditionally the different aspects of the design process are tackled separately by different departments within a company....

Hong, Z. (author)
Reducing weight and improving strength of structures have always been major design goals in the aerospace industry since its inception. In particular, strength directly affects the safety and serviceability of an airplane and is therefore of great importance in structural design. Improving the strength of an airframe can effectively increase its...

Jovanov, K. (author)
Multi-disciplinary design optimization (MDO) is a field that has gained traction in recent years. It can be distinguished as a methodology that promotes a simultaneous change in design features associated to multiple disciplines in order to achieve the best possible design of a coupled multi-disciplinary problem. A typical application in...

Ponnusami, S.A. (author)
Research in the field of self-healing materials gained significant attention in the last decade owing to its promise of enhanced durability of the material components in engineering applications. Though the research has led to several successful demonstrations, extensive experimental tests will be required for a successful demonstration. Further...

Werter, N.P.M. (author)
In order to accommodate the growth in air traffic whilst reducing the impact on the environment, operational efficiency is becoming more and more important in the design of the aircraft of the future. A possible approach to increase the operational efficiency of aircraft wings is the use of aeroelastic tailoring, by taking advantage of the...

Peeters, D.M.J. (author)
The use of composite materials in airplanes has been increasing over the last decades, mainly due to the high strength-to-weight and stiffness-to-weight ratio of composites. Traditionally, the possible fibre angles are often restricted to 0°, ±45° and 90°, referred to as conventional laminates. However, with the rise of fibre placement machines,...

Zheng, W. (author)
A recently developed fiber placement architecture, AP-PLY, has been shown to give significantly improved damage tolerance characteristics of composite structures. The behavior of delaminations resulting from low speed impact damage is of particular concern. Major attention has been paid to expand current knowledge on the delamination response of...

Wang, Z.P. (author)
The recently developed isogeometric analysis (IGA) was aimed, from the start, at integrating computer aided design (CAD) and analysis. This synthesis of geometry and analysis has naturally led to renewed interest in developing structural shape optimization. The advantages of using isogeometric analysis in shape optimization are embodied in its...

Guo, Y. (author)
The conceptual ideas behind isogeometric analysis (IGA) are aimed at unifying computer aided design (CAD) and finite element analysis (FEA). Isogeometric analysis employs the non-uniform rational B-spline functions (NURBS) used for the geometric description of a structure to approximate its physical response in an isoparametric sense. Due to the...
