Validation of Accelerated Reliability Test Techniques of Industrial Components Using Finite Element Analysis

Abstract:

The purpose of this paper is to validate the accelerated testing methodology of a component from the field of aviation (supple platinum) using the standard calculation method and the analysis with finite elements. The specimens made out of supple platinum from the helicopter’s structure have been put through to accelerated experiments. Using the data resulted from the analysis with finite elements, the data resulted from resistance calculations and the experimental data obtained from the testing of specimens, a comparative study was realized between the specific strain and the normal stress that were obtained. From the results of this comparative study, it is obvious the fact that the method of analysis with finite elements is an efficient instrument to validate the experiments.
