(5) This calculation of aerodynamic property lift is used to simulate the wing loading on the wing surfaces using isotropic materials in design.
Now-a-days advance aluminum are mostly used in wing construction although composite materials are the first choice due to tremendous mechanical load bearing capacity, light weight, high thermal and corrosive resistance.

Magnesium alloy strips prepared by single roll casting are suitable for Mg-based functional materials but not for structural materials because of low quality or high cost.
Meanwhile some key technologies such as smart delivering of magnesium alloy melt and design and materials of melt distribution and tip systems have been solved as well.
Single roll casting will be used for Mg-based functional materials.

Not only seismic activities but also radical change in service purpose, material deterioration over time and an enhancement of lateral load demand could require upgrading structural performance.
The buckling of the brace compression members and material softening due to Bauschinger effect cause brittle failure under cycling loading.

Therefore, the design principle of SISDG is to improve the strength of CSM and to resist shrinkage cracks or temperature shrinkage crack, coarse aggregate should form a stable framework; in order to reduce the coefficient of contraction and thin "surplus" cement paste, the fine aggregate should closely fill the void of framework formation; in order to improve the structure durability and performance, the binding materials should coat aggregate to make the loose mineral aggregate forms a whole; in order to better simulate the vibratory road roller’s compaction on the road material in construction site, using vibration method to compact specimen.
