澳洲研究学论文代写：有限元模型仿真所涉及的过程

有限元模型仿真所涉及的过程如下:第一部分:该过程可以定义为两个不同的通道和一个支撑构件，通过与其他几个螺栓连接而得到。该部分用于调查。图中螺栓节点已经提到。材料性能:研究所需的材料性能包括杨氏模量和泊松比的确定。杨氏模量可定义为线性弹性固体材料的力学性能。它给出了应力与可观察到的材料整体应变值之间存在的关系的定义。杨氏模量的单位和压强的单位是kN/mm2。这是因为应力的单位是压力，应变的单位是较小的。材料中的杨氏模量约为210kn /mm2。

泊松比另一方面可以定义为横向测量的比例减小与可弹性拉伸的试样总长度比例增大的比值。当材料在任何一个特定方向上被压缩时，它倾向于在两个垂直于压缩方向的其他方向上进行膨胀。这种情况下泊松比的值为0.3。根据Sabbagh等人(2013)的表述，屈服应力的整体值在308 N/mm2左右，极限应力的值在474 kN/mm2左右。根据Sabbagh等人(2013)进行的试样试验，不同的材料模型被假定为具有双向各向同性应变硬化。可以发现，主应力的最大值比总应力高10%左右。

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.
