The Test of Aircraft Material with Performance Parameters Xia Ren1,a, Lianxiang Ma2,b 1,2College of Electromechanical Engineering, Qingdao University of Science and Technology, Qingdao, Shandong Province, China arenxia1229@163.com, boldhorse@qust.edu.cn Keywords: ABAQUS FE analysis; Aircraft tire; Uniaxial tensile test Abstract: This paper uses the ABAQUS finite element analysis software for modeling and nonlinear analysis of aircraft tires.
Paper H44.5 × 16.5-21 aviation tires, The plastic material of the tire subjected to uniaxial stretching to obtain a rubber such as Young's modulus, Poisson's ratio of the material parameters.
For the incompressible material, we choose Yeoh model to describe mechanical property better in ABAQUS.
Because the rubber material adopt the hyperelastic unit simulation, we only need the mechanical constants of materials but Poisson’s ratio.
Each of the rubber material constitutive model are compared from the perspective of material nonlinearity.

Of the semiconductor materials, ZnO shows a significant photocatalytic potential because of its direct wide band gap (Eg = 3.37eV) [2-3].

Nano- and new materials technology are strong research and product development targets, and new applications and solutions arise all the time.
The ongoing trend for miniaturization of different devices and improvement of property of materials require improvements in technology.
Many such tasks are solved by means of nano-technology and nano-materials.
Faster computers, advanced pharmaceuticals, controlled drug delivery, biocompatible materials, nerve and tissue repair, surface coatings, better skin care and protection, catalysts, sensors, telecommunications, magnetic materials and devices – to name but a few of the areas where nanotechnology will have a major impact.
Sophisticated materials and materials systems with novel properties and unheard of performance will have to be conceived and designed in the decades to come.

The single spinel phase powder was obtained when the precursor materials with a carbon powder of 5% in mass were used.
If using other materials to replace the iron powder as the fuel to prepare the Ni-Cu-Zn ferrite powders, it will avoid precursor materials mixed non-uniform and sintering temperature uneven because of oversize of the iron powder particle-size [5-8].

Some scholars tried to establish strength theory of materials based on energy principles, and have made gratifying progress.
We know that the elastic strain energy is the energy driving material failure, but the volumetric strain energy is beneficial to stability, this is because rock, soil and concrete belongs to frictional materials.
Xie et al suggested a failure criterion for rock materials based on the releasable elastic strain energy before failure[13], which can be called as the energy release rate theory.
