# 澳洲研究学论文代写：有限元模型仿真所涉及的过程

The processes which are involved for the simulation of FEA model is as follows:Part: This can be defined as two different channels and one support member which can be obtained by connecting with a number of other bolts. The part is used for the investigation. The bolt nodes in the given diagram have been mentioned. Material properties: Material properties which are required for the investigation include the finding of Young’s Modulus and the Poisson’s ratio. Young’s Modulus may be defined as the mechanical property which belongs to the linear elastic solid materials. It gives the definition of the relationship that exists between the stress and the value of the overall strain which may be observed in a material. The unit of young’s modulus as same as the unit of pressure which is kN/mm2. This is because the unit of stress is pressure and strain is unit less. The value of Young’s modulus in the material is found to be around 210 kN/mm2.

Poisson’s ratio on the other hand can be defined as the ratio of the proportional decrease of the lateral measurement to the proportional increase in the overall length of the sample of the material which can be elastically stretched. Whenever the material is compressed in any one specific direction, it tends to do the expansion in the two other directions which may be perpendicular to the direction of compression. The value of Poisson’s ratio in this case is found to be 0.3. As per the statement of Sabbagh et al (2013), the overall value of yield stress was found to be around 308 N/mm2 and the value of the ultimate stress has been found to be around 474 kN/mm2. The different material models have been assumed to be a bilateral and have the isotropic hardening of strain as per the coupon tests which are conducted by Sabbagh et al (2013). The maximum value of principle stress can be found to be around ten per cent higher than the overall stress.
