Cover The 21st century marks the era where ultra-high strength and light weight alloys and composites will be used more sparingly for fabricating jet transports to enhance fuel efficiency. Thus, fatigue crack initiation and propagation may become comparably significant with respect to airworthiness. For this, the crack initiation behavior of high-cycle and very-high-cycle fatigue is essentially vital to the control of the fatigue life, for which the cracking origination is from the interior of material instead of from surface and presents a specific pattern of “fish-eye” and “fine granular area (FGA)” which takes a predominant part of total fatigue life. The background of this cover is an image of fatigue crack origination from the interior of material for a high strength steel showing “fish-eye” and FGA originated from an inclusion.
Aviation safety is the theme given to the International Conference on Airworthiness and Fatigue: 7th ICSAELS Series Conference, Beijing, China, held on 25–27 March, 2013. This event was initiated by the International Center of Sustainability, Accountability, and Eco-Affordability for Large and Small (ICSAELS) and the Institute of Mechanics, Chinese Academy of Sciences.
Energy efficiency of aviation transport is vital to the conservation of natural resource that requires for a common understanding to address the mechanical, electrical and chemical effects, as well as the multiscale material constituents. The Industrial Revolution has already paved the way from the large scale systems to the very small. Miniaturization and nanotechnology have been the new challenge. Cutting edge scientific and technological endeavors will not mature without paying dues to learning. The interaction of technology and financial measure is an acute challenge of the 21st century. The outsourcing of core technology and to use financial measure as a gauge of net profits should be constrained by technical performance.
In this respect, what was established for mechanical effects can be scaled to balance with chemical effects, though the sustainability and stability of the systems can vary. Spatial-temporal scaling of the mechanical, material structural and chemical entities is necessary in design. This area of research is known as “Multiscaling and Mesomechanics”. More specifically, the three familiar quantities of specific energy density, volumetric energy density and specific power density have been used commercially for specifying the performance of the lithium-ion battery. In other words, the power dissipation behavior of the lithium-ion battery is, in principle, the same as that for the fatigue of metals, except for the difference in space-time scale range. “Power Dissipation Scaling” cannot be over emphasized in order to link the chemical to the mechanical effects that are less distanced from the sensory perception. Hopefully, the aforementioned spirit will be reflected by the theme of “Airworthiness and Fatigue” of this conference. Again, safety, defect, strength and fatigue cannot be separated from overall technical considerations.
The original concept and idea to hold this conference was materialized by the members of the Scientific Advisory Committee. Their contributions can be clearly evidenced from the technical presentations and have laid the foundation to carry the torch to the destination of aviation safety. This is only the first leg of the relay.
This special issue of Science China Physics, Mechanics & Astronomy contains twelve papers selected from the Proceedings of International Conference on Airworthiness & Fatigue, with authors from Australia, Russia, Greece, Italy, United States and China. The original conference manuscripts have been extended to the journal style papers by the authors and have been subjected to normal peer review processing. We hope that this collection of the papers with the current progresses in Airworthiness and Fatigue is of benefit to the relevant research and application community.
