“…Lightweight materials such as magnesium and its alloys are of great interest for the industrial sector. Potential applications can be found in the automobile industry and in civil engineering as structural components (Dieringa and Kainer, 2013), in batteries as anode material (Deng et al, 2018;Höche et al, 2018) and in medical engineering as biocompatible, resolvable implants (Kirkland, 2012;Luthringer et al, 2014). The aspects of applying magnesium based materials in vehicle concepts have been widely discussed (Dieringa et al, 2007;Dieringa and Kainer, 2009;Dieringa and Bohlen, 2016) with the result that functionalizations of magnesium alloys are feasible (Xianhua et al, 2016).…”

Novel magnesium-based materials are ideal candidates for use in future aviation vehicles because they are extremely light and can therefore significantly increase the range of these vehicles. They show very good castability, are easy to machine and can be shaped into profiles or forgings to be used as components for next generation aerial vehicle construction. In the case of a large number of identical components, high-pressure die casting of magnesium alloys is clearly superior to high-pressure die casting of aluminum alloys. This is due to the lower solubility of iron in magnesium and thus tool/casting life is significantly longer. In addition, the die filling times for magnesium high-pressure die casting are approximately 30% shorter. This is due to the lower density: aluminum alloys are approximately 50% heavier than magnesium alloys, which is a significant disadvantage for aluminum alloys especially in the aerospace industry. There are cost-effective novel die casting alloys, besides AZ91 or AM50/60 such as DieMag633 or MRI230D, which show very good specific strength at room and elevated temperatures. In the case of magnesium-based wrought alloys, the choice is smaller, a typical representative of these materials is AZ31, but some new alloys based on Mg-Zn-Ca are currently being developed which show improved formability. However, magnesium alloys are susceptible to environmental influences, which can be eliminated by suitable coatings. Novel corrosion protection concepts for classical aerial vehicles currently under development might suitable but may need adaption to the construction constraints or to vehicle dependent exposure scenarios. Within this mini-review a paradigm change due to utilization of new magnesium materials as drone construction material is briefly introduced and future fields of applications within next-generation aerial vehicles, manned or unmanned, are discussed. Possible research topics will be addressed.

Abstract-Numerical calculations of large scale corrugated core sandwich structures are, due to their characteristic cross sections, generally very labor-intensive and costly. With the application of effective orthotropic FE-shell elements, which are based on a homogenization technique, modeling and computation of these structures can be carried out more efficiently. In the present paper an analytical homogenization framework is presented. For the verification of the analytical stiffness predictions a parametric study is performed employing FE-unit cell analyses. Numerical analyses of four-point bending tests employing effective orthotropic shell elements are performed in order to demonstrate the effectiveness of these elements. Finally, the numerical bending test results are verified experimentally.Index Terms-Corrugated core sandwich structures, finite elements, lightweight design, orthotropic material behavior.
