Unconventional aircraft, such as the Flying-V, are projected to achieve more than 20% fuel savings when compared to conventional configurations. However, these unconventional aircraft configurations pose a unique set of design...conference paper 2024

Yao, Liaojun (author), Chuai, Mingyue (author), Lyu, Zhangming (author), Chen, Xiangming (author), Guo, Licheng (author), Alderliesten, R.C. (author)Methods based on fracture mechanics have been widely used in fatigue delamination growth (FDG) characterization of composite laminates. These methods are based on the similitude hypothesis. It is therefore important to have appropriate parameters to well represent the similitude, which is useful for fatigue delamination test standard...journal article 2024

Ji, C. (author), Hu, Jiqiang (author), Alderliesten, R.C. (author), Yang, Jinchuan (author), Zhou, Zhengong (author), Sun, Yuguo (author), Wang, Bing (author)This paper aims to illustrate the effect of the impact damage on fatigue behavior of CF/PEEK-titanium hybrid laminates. To achieve this end, a fatigue life model was proposed to predict the S–N curves of the laminates at various initial impact energy levels and stress ratios based on the energy dissipation approach. The energy dissipation...journal article 2024

Anand, S. (author), Alderliesten, R.C. (author), Castro, Saullo G.P. (author)To design crash structures for disruptive aircraft designs, it is required to have fast and accurate methods that can predict crashworthiness of aircraft structures early in the design phase. Axial crushing is one of the key energy absorbing mechanisms during a crash event. In this study, various analytical models proposed for calculation of...journal article 2024

Biagini, D. (author), Pascoe, J.A. (author), Alderliesten, R.C. (author)Although several studies have been performed, the compression after impact (CAI) failure of CFRP is still not entirely understood. It is still unclear what sequence of events determines the onset of failure in CAI tests and how the different damage modes are involved in this process. To experimentally investigate this matter, the present work...journal article 2023

Alcaraz, Mathilde (author), Alderliesten, R.C. (author), Mosleh, Yasmine (author)Fibre metal laminates (FML) were originally developed as a hybrid material, to create synergy between the impact resistance of metals and excellent fatigue and corrosion resistance of fibre reinforced polymers, and to overcome the shortcomings of monolithic materials. Yet, the scope of the FML concept is predominantly limited to GLAss REinforced...abstract 2023

Pascoe, J.A. (author), Tu, W. (author), Biagini, D. (author), Alderliesten, R.C. (author)Fibre reinforced polymer composites have found increasing use in aircraft structures. This means that fleet managers need damage assessment tools for such materials, in order to decide on appropriate sustainment strategies. Developing such tools is hindered by the difficulty of generalising from lab tests to predict the behaviour of full-scale...conference paper 2023
