Failure Analysis of Polycarbonate part by Using Finite Element Simulation

摘要

The designing, manufacturing and testing steps are the important steps in product design and development processes. It begins with designing step follow to required dimensions and shape that conform to its applications. Then, parts are manufactured and tested for performance evaluation and making of corrective deign. These steps generally consume long time and high expense. It should be more advantage, if these steps could be carried out by computer simulation. Therefore, this research aims to use finite element method to simulate and analyze failure of the polycarbonate product. Fixtures are designed and made for tensile testing of the current product. The result comparison between simulation and testing shows approximately 90% of accuracy. It implies that simulation model and software are verified. The results from this research were used to improve the current design. It is expected that using of simulation techniques could significantly reduce development time and expense.
