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.

Uniformity of material removal rate (MRR) is of great significance to wafer planarization process.
But there is no chemical material in lapping, so CMP material removal rate model is not suitable for lapping.
