Reliability Evaluation Of FPC Under Bending Stress
In this paper, finite element analysis method is applied for modeling and simulation of FPC to analyze its mechanical performance under the constant stress. In the simulation process, the bending method used in this research is to fix the middle of the FPC and to impose load on both sides. The results of Von Mises stress distribution between the layers of FPC are presented and analyzed with the knowledge of material mechanics. In addition, the length and the thickness of layers of FPC are taken as optimization variables. With the variables change, there are many different cases. This paper presents the stress comparison with different lengths and thickness of layers of FPC model. The simulation results show that there are different stresses between the layers of FPC model. The disbonding failure may occur between the layers of FPC under high-cycle load and the stress between layers will be reduced by changing the length of model. With ANSYS, the fatigue life of FPC is calculated approximately. The analysis result may provide some help on FPC design and manufacturing.
